What is an Isolation transformer and its importance in Storage Solutions? Domestic and industrial users face severe power shortages in most parts of the world. In that scenario, they have no other option but to seek help from power backup technologies such as UPS (Uninterrupted Power Supply) and battery inverters/Solar Inverter/Solar PCU/Lift Inverter/Lift UPS/Industrial Inverter/Energy Storage Solutions/ERD etc.
Over the years, inverter/UPS technology has undergone multiple development phases. What you find today is much more efficient and of higher quality than was available a few years ago. One such improvement is the addition of isolation transformers to the UPS/inverters/lift inverters/Battery ESS/Solar hybrid PCU etc.
What is an isolation transformer?
Isolation, also called galvanic isolation, implies that no direct path exists for the current to flow from the source to the load. An isolation transformer provides isolation between the electrical devices and the source powering these devices. In other words, the output power circuit is electrically and physically isolated from the input power circuit with an isolation transformer. As a result, the isolation transformer provides safety to the users and the appliances.https://en.wikipedia.org/wiki/Isolation_transformer
Apart from isolation transformers, other types of transformers include Inverter duty transformers, Instrument transformers, and Inverter transformers or electronic transformers. However, this article focuses on isolation transformers, their benefits, and why they should be used in an inverter/UPS/Lift inverters/Battery ESS/Solar Hybrid PCU etc.
Why should you use an isolation or galvanic transformer in a UPS/inverter system?
As a standard practice, having the right power solutions to power your domestic appliances or perform industrial operations is essential. In this regard, a UPS/inverter is gaining popularity due to its ability to provide efficient, high-quality, and safe power solutions under imperfect power situations. However, we can further improve the working of a UPS/inverter system by embedding it with an isolation transformer. Here is why it is essential to have ups with an isolation transformer.
Isolation transformer circuit
Isolation/Galvanic transformer
Protect the equipment
Like any other transformer, an isolation transformer can also be developed as a step-up or step-down transformer to spike up or down the voltage. The galvanic isolation protects the equipment from unnecessary damage by detaching them from the powering alternating current.
The safety mechanism of an isolation transformer becomes more pronounced when there are unpredictable altered voltage disturbances. In such a situation, an isolation transformer separates the load from the circuit, thereby saving the appliances to your UPS/inverter supply current. Thus, all the sensitive equipment in your office or home will continue working without any data, operational, or financial loss.
Bestows robustness
UPS/inverters systems having isolation transformers are more flexible, efficient, and robust. Several equipment and appliances, such as computers and sensitive instruments, work better when your UPS/inverter has an isolation or galvanic transformer. This is why there is a greater demand for isolation transformers in UPS/inverter systems.https://suvastika.com/high-vs-low-frequency-inverters-ups-comparison/
Faultless voltage conversions
USP/inverters are used to power various appliances and equipment, but not all devices have the same voltage requirement. So, it is possible for the output voltage to not align with the voltage requirements of an appliance.
Voltage conversion is needed when the output voltage is more or less than the required voltage. Here comes the need for an isolation transformer. It will increase or decrease the output voltage to match the appliance requirement.
Safety against shocks
UPS/inverter systems provide high-frequency power to the equipment. However, equipment often lacks ground safety potential, leading to shocks and electrocution. In the presence of an isolation transformer, such damages can be avoided with the isolated safety mechanism. Even the equipment without ground safety gets sufficient protection.
Ensure the safety of sensitive Appliances.
An isolation or galvanic transformer is indispensable for the UPS/inverter systems providing a backup supply to sensitive equipment such as heart monitors and other equipment in the hospital that must be running all the time.
Safe and easier maintenance
Servicing and maintaining an isolation transformer-based UPS/inverter system is much safer and easier as it provides safety against electrocution. Hence, the technicians can work on and test them without the fear of getting an electric shock.
Reduce fault current supply.
Fault currents and power issues are common occurrences. However, an isolation transformer can minimize its effects by using Faraday shields. And you always get an adequate and perfect power supply from your UPS, ensuring that all the appliances work properly.
Harmonics management
Noises and harmonics variations are not unheard-of in power supply. When the UPS provides output current at various frequencies, facing noise disturbances is possible. As a result, the end-use power quality is affected. You must note that noise disturbances refer to electric and magnetic field disturbances, not sound disturbances. These noise disturbances can significantly impact the reliability of sensitive equipment such as those used in the medical field. Using a UPS/System with an isolation transformer is hailed for its ability to reduce noise disturbances.https://en.wikipedia.org/wiki/Galvanic_isolation
Isolated vs. non-isolated transformer
An isolated transformer separates the circuit from the AC line. It is earthed, housed at a safe location, and connected to a power supply through a short earthed connection. As a result, if the user comes in contact with any part of the electrical circuit, the current does not find any return path through the user, thereby reducing the electrocution hazard.
You can use the connected appliances in wet, damp, indoor, and outdoor situations without any risk of electrocution, even when the connected tool or device is not earthed.
The case of a non-isolated transformer is quite the opposite. The circuit is not shielded from the AC line; hence electrocution is possible.
Benefits:
Isolation transformers offer several benefits when used in conjunction with Inverters,Uninterruptible power supplies (UPS), Lift Inverter, Online UPS, Solar PCU, Solar Inverter and lithium Inverters
Enhanced Safety: A key advantage is improved safety. The transformer creates a physical separation between the utility power input and the equipment connected to the UPS output. This isolation eliminates the risk of shock from ground faults that might occur on the utility side.
Improved Power Quality: Isolation transformers can help to reduce electrical noise and transients on the power line. This ensures cleaner and more stable power reaches the sensitive equipment protected by the UPS.
Ground Loop Mitigation: Ground loops arise from minute voltage differences between grounding points in a system. Isolation transformers help to eliminate these ground loops, preventing issues like hum or interference in sensitive electronic devices.
Surge Suppression: In some cases, isolation transformers can provide some degree of surge suppression, offering additional protection against transient voltage spikes.
Configurable Voltage Output: While isolation is the primary function, some transformers can also be designed to step up or step down voltage levels to meet the specific needs of the equipment being powered by the UPS.
Overall, isolation transformers contribute to a more robust and reliable UPS system, safeguarding equipment and ensuring optimal performance.
Conclusion
What is an Isolation transformer and its importance in Storage Solutions is very well explained in this article. An isolation transformer makes working with AC-powered equipment much safer. Embedding an isolation transformer in your UPS/inverter/Lift Inverter/Battery Energy Storage systems/Solar hybrid PCU system makes it a more efficient and safer option for powering sensitive instruments in domestic and industrial settings. Now that you know the immense advantages of an isolation transformer-based UPS/inverter, always consider this technology and buy the UPS from a trusted isolation transformer manufacturer such as Su-vastika. The company has been developing reliable heavy-duty inverters/UPS with isolation transformers for various domestic and industrial applications.

The Lifts are stopped suddenly when power fails or during power outages which is a big shock for the people travelling in the lifts and Elevators.
We have designed a lift UPS which works on the Three-phase Lift inverter system and powers the lifts for smooth running in case of power outages or power failure. This is called an Emergency Rescue Device, which keeps the lift working uninterruptedly in case of power failure or voltage fluctuations
The lift suddenly gives a few jerks and stops, lights are blinking on and off, and a deadly silence engulfs everything. On top of that, you are alone, and there is no one to hold on to for support. Pretty scary, right? This is just a glimpse of what happens when a lift stops working midway….
When the energy supply to the lift stops, the elevator car bounces back and forth like a rocking boat and makes rough metal sounds. It falls with lightning speed, though not a free fall but very close to it and extremely dangerous for people inside. All this happens in a few minutes, so you struggle to understand the situation.
What would you need in this situation?
Power backup for lifts in case of Power failure, right?
Today we will introduce you to an Emergency Rescue Device (ERD)/Lift UPS Lift Inverter that can be installed in the Machine room of the lift or elevators so that passengers don’t face any life-threatening situations in case of power failure.
But before that, look at things that can happen to people when they are stuck in an elevator.
What can happen to people when they are stuck in an elevator?
Various people report different experiences about the time they were stuck in an elevator, but the most common ones are:
Panic attacks: Getting trapped in an elevator is alarming. When the lift stops with a jerk, most people’s first reaction is panic. Their hearts start pounding heavily, and they experience a sinking feeling. Preexisting health conditions such as asthma are known during a panic attack, often requiring emergency help.
Confusion: When the lift stops, all the lights turn off since everything is powered by electricity from the main supply. This complete darkness in the lift makes matters worse for people. It creates confusion, especially when the lift is cramped with passengers. This confusion also causes their fight-or-flight response to go helter-skelter.
Claustrophobia: Even for people with a mild fear of enclosed places, getting stuck in a lift that stopped due to a power outage can trigger their phobia. The particular term for having a fear of riding elevators is called Elevatophobia.
Two types of phobia that lead to Elevatophobia are:
Claustrophobia: fear of sealed-off spaces.
Agoraphobia: fear of being confined without a way to escape.
When a lift stops with a jolt, people may experience a sharp decline in blood pressure, troubled breathing, sweating and shaking, hyperventilation, dizziness, and dry mouth. Some people also feel choked even with proper ventilation in the lift. According to the American Journal of Psychology, this situation can become life-threatening for passengers, especially kids, pregnant women, the disabled, and the elderly.
What is an Emergency Rescue Device for lifts?
An Emergency Rescue Device, also called an ERD, is a device installed in lifts that comes into action during power outages that halt the lift’s functions. This emergence apparatus provides power to the lifts with a 3-phase power supply when electricity from the mains supply disconnects.
An ERD differs from a standby generator or an emergency power system. Unlike them, it provides near-instantaneous fortification from input power disruptions by storing energy in batteries through a dedicated Power Bank. Its stored energy is enough to protect you from getting stuck due to power failures, technical hitches, and other troubling situations. ERD power also eliminates the need for using a backup generator.
How is an ERD different from an ARD?
ERD is the latest technology, while ARD (Automatic Rescue Device) has been used for quite some time. In the event of power failure, a lift equipped with this ERD continues to move smoothly.
Opposite to ERD, an ARD technology starts working 30 seconds to 1 minute after the lift stops. The lights are switched on, and the lift takes you to the next floor and opens the door for a safe exit. Once the exit is complete, the generator kicks in and starts its reset process.
The lift goes straight to the basement and takes at least 10 minutes to reset and start its operations. During this time, people remain stuck in the lift, panicking and praying for their dear life.
In the case of an ERD, the passenger does not even feel any change when the lift transitions from grid supply to ERD power if it continues to work for hours.
ARD is not a backup device. Its job is to take the lift to the nearest floor and open the door for the passengers. In contrast, an ERD is a powerful backup device.
With ARD technology, the total time from a power outage to the lift door opening is approximately one minute. Under normal circumstances, waiting for one minute is no hassle. But when confined in a lift, even one minute can create panic and confusion among passengers or cause medical emergencies such as heart failure.
Why is an ERD better than an ARD?
ERD is much superior technology to ARD. Benefits of ERD include:
Smoothoperation
When an ERD is fitted into an elevator, the lift works smoothly on the battery without any jerks. The switching time is zero; the lift does not stop even for a moment, and unlike ARD, no generators are required. The lift electronics and electrical systems keep running without any breaks. The smooth functions eliminate the odds of lift failures and considerably reduce maintenance costs.
High power quality
Compared to the power supplied by Electricity companies, ERD delivers high-quality pure sine wave power to the lift. The power frequency is exactly 50Hz, with no chance of fluctuations.
Power quality supplied by an ERD/lift UPS can not be compared with any generator or existing ARD system. ERD supplies stable and clean power in an economical and environmentally-friendly fashion as it only caters to the lift load.
Features of a lift embedded with Su-Vastika Lift UPS/ERD
The lift embedded with Su-Vastika ERD provides passengers with the utmost convenience and safety. An Electronic Control Unit is installed inside the lift to indicate to the passengers whether the lift is working on the grid or ERD power.
The passengers cannot feel the change when the lift transition from one power source to another due to zero switching time. Therefore, informing the passengers that the lift is working on emergency backup is necessary.
ECU system tells the passengers about power transition through its announcement feature. The passengers can also see whether the lift is being operated on grid supply or ERD power through a display installed in the lift.
In case of low battery or when it is discharged, the display indicates the low battery. At the same time, the embedded speakers announce for the safety of passengers, indicating that the battery is low.
Why choose Su-Vastika lift UPS ERD technology is the right decision?
No one wants to ride on lifts that carry the risk of stopping midway and making you claustrophobic. Places like shopping malls, hotels, and hospitals, require lifts for customers’ convenience. But without ERD, there is a chance that customers will experience stopping jerks and falls in lifts.
Such bad experiences are enough to fend off your customers. Therefore, installing ERD from trusted manufacturers like Su-Vastika is the right thing to do. Some features making Su-Vastika ERD technology a superior choice include:
Su-Vastika has a technology patent for their ERD technology
Their machines can be designed for small to big lifts up to 500 KVA load
Their ERD technology supports lead-Acid as well as lithium batteries
The technology is efficient enough to provide clean power backup for up to two days
This technology has BIS (Bureau of Indian Standards) Certification (third-party guarantee of safety, quality, and reliability)
It is a low-maintenance machine
Their ERD technology supports solar power too
Conclusion
Lift UPS/Lift inverter is an old technology, and ERD technology is superior and more reliable than the previously used ARD technology. It ensures that the lift function never stops and people with or without any underlying illnesses such as claustrophobia never feel the fear of getting trapped in an elevator ever again.
