Residual Voltage Transformer is one of the transformers that are used for the purpose of detecting unbalanced voltage in a three-phase system and supplying voltage to a directional earth fault relay. When it comes to normal operating conditions, the summation of three-phase voltage is zero. However, in the case of a single-phase fault, the scenario remains flexible and there exists a residual voltage.
These transformers are designed for a range of up to 145kv. They are suitable to be used for capacitor bank protection. They feature to detect the neutral to ground fault conditions on star-type connections. The insulation contains an oil-paper combination and the oil impregnation is done under a high degree of vacuum.
Residual Voltage
In general, residual voltage is generated by connecting secondary of three-phase voltages. Using three-phase voltages is not very expensive. We manufacture top-class residual voltage transformers to meet your needs. Like, voltage transformers help step down the voltage from a high value to a lower value. And it is suitable to measure instruments like energy met4ers, voltmeters and protective relays. A Residual Voltage Transformer (RVT) is a specific type of Voltage Transformer, which is used for the purpose of protecting the Capacitor Banks from Earth’s fault.
Advantages Of Our Transformers
The Residual Voltage Transformers designed by us come with multiple benefits. They are designed to offer electrical isolation between high voltage power circuits and measuring instruments. They can help reduce the insulation cost of measuring instruments. These transformers also make sure the safety of operators and lower utility losses. They can protect many devices during fault conditions.
