Voltage Transformers
High Voltage Transformers
High Voltage Potential Transformers (HV-PT) are manufactured for the range 245 kV through 123 kV voltage class. The HV-PTs are of outdoor type of either dead tank or cascade type design. The insulation is finely graded and consists of oil-paper combination. The oil impregnation is done under a high degree of vacuum with excellent monitoring and control of dissipation loss factor (tan delta). HV-PTs are hermetically sealed with either stainless steel bellows or nitrogen cushioning as per customer specification. Conformance can be made in accordance to IS, IEC, BS and ANSI standards.

Medium Voltage Transformers
Medium Voltage Potential Transformers (MV-PTs) are manufactured ranging from voltage class 11 kV through 66 kV. MV-PTs are of inductive and outdoor type with dead tank design optimized for the lowest oil volume. The insulation is based on oil-paper combination. The oil impregnation is done under a high degree of vacuum with excellent monitoring and control of dissipation loss factor (tan delta). MV-PTs are hermetically sealed with either stainless steel bellows or nitrogen cushioning as per customer specification. Conformance can be made in accordance to IS, IEC, BS and ANSI standards.
