Capacitor Voltage

Trench is a recognized world leader in the design and manufacture of high voltage equipment for application in electric utility and high energy industrial systems. As part of Trench's product scope, the Company produces a diversified range of Instrument Transformers for transmission class Instrument Transformers include: Voltage (Potential) Transformers (inductive and capacitive types), Current Transformers and Combined Instrument Transformers (voltage and current Capacitor Voltage Transformers convert transmission class voltages, 72.5 - measurable values with high level of fidelity, used for...

Bellows puncture pin designed to provide for the release of internal pressure in the event of abnormal service conditions. Puncture pin operation results in an early indication to safely remove the unit from service. Line Trap mounting directly onto the CVT or CC is possible with some ratings (please consult factory). Guaranteed minimum creepage distances of our standard porcelain and composite insulators exceed ANSI and IEC requirements (referto datasheet information below). Higher creepage distances are available for higher pollution applications. Maintenance-free oil filled cast aluminum basebox...

Electrical Performance Characteristics Notes: [1] Two main windings are supplied as standard, with a third auxiliary winding available as an option. [2] The accuracy class for total simultaneous loading is equal to the values given for the main winding(s). [3] Higher burdens on special request.
