Neutral Current Transformers

High Voltage Neutral Current Transformers

High Voltage Neutral Current Transformers (HV-NCT) are manufactured for the range 245 kV through 123 kV voltage class. HV-NCTs can be used for capacitor bank protection to measure the differential current flow in H-type connections. The HV-NCTs are of wound and outdoor type with dead tank 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-NCTs are hermetically sealed, with either stainless steel bellows or nitrogen cushion. Conformance can be made in accordance to IS, IEC, BS and ANSI standards. Technical details are same as that for high voltage current transformers.

Medium Voltage Neutral Current Transformers

Medium Voltage Neutral Current Transformers (MV-NCT) are manufactured for the range 72.5 kV through 11 kV voltage class. MV-NCTs can be used for capacitor bank protection to measure the differential current flow in H-type connections. The MV-NCTs are of wound and outdoor type with dead tank 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 MV-NCTs are hermetically sealed, with either stainless steel bellows or nitrogen cushion. Conformance can be made in accordance to IS, IEC, BS and ANSI standards. Technical details are same as that for medium voltage current transformers.
