Residual Voltage Transformers
Residual Voltage Transformers (RVTs) are manufactured for the range 11 kV through 33 kV voltage class. RVTs can be used for capacitor bank protection by detecting the neutral to ground fault conditions on star-type connections. The insulation consists of oil-paper combination with the oil impregnation done under a high degree of vacuum. Conformance can be made in accordance to IS or IEC standard.
