High Voltage Current Transformers
High Voltage Current Transformers (HV-CT) are manufactured for the range 245 kV through 123 kV voltage class. The HV-CTs are of wound and outdoor type with either dead tank or live tank (head 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). All HV-CTs are hermetically sealed, with either stainless steel bellows or nitrogen cushion. Conformance can be made in accordance to IS, IEC, BS and ANSI standards.

Medium Voltage Current Transformers
Medium Voltage Current Transformers (MV-CTs) are manufactured ranging from voltage class 11 kV through 72.5 kV. Typically MV-CTs are wound-type with dead tank design and of outdoor type although live tank design and indoor type is also manufactured. 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). All MV-CTs are hermetically sealed, with either stainless steel bellows or nitrogen cushion. Conformance can be made in accordance to IS, IEC, BS and ANSI standards.
