Residual Voltage transformer
Residual Voltage Transformers are manufactured for the range upto 145kv. 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 standards.
Neutral Current Transformer
Neutral current transformers are manufactured for the range upto 145kv. NCT can be used for capacitor bank protection to measure the differential current flow in H-type connections. The 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). Conformance can be made in accordance to IS standards.
Voltage transformers
Instrument Transformers are used for measurement and protective application, together with equipment such as meters and relays. Their role in electrical system is of primary importance as they are means of “stepping down” the voltage of a system to measurable values, such as 110V or 100V in the case of a voltage transformer. This offers the advantage that measurement and protective equipment can be standardized on a few values of voltage.
We design, manufacture and supply outdoor, oil cooled voltage transformers by high-qualified experience workforce. We provide range of transformers offered upto 145KV that makes these transformers suitable for high-end requirement of various applications.
