Instrument Transformers

Capacitive Voltage Transformer

Application: Used in HV & UHV power systems for voltage and power measurement, relay protection, automatic control, etc., and can be concurrently used as coupling 
capacitors in the power line carrier communication system. 
Standard: IEC60044-5
Features: C-type core, seismic design, world’s advanced transient response, first built-in micro-positive pressure oil compensation.

HV Current Transformer (Suspend Production)

Application: used for voltage signal switching of HV no-current line, and provide isolation between the electrical apparatus under repair (like HV busbar, circuit breaker, etc.) and the HV live line. Voltage level: 110?220kV.
Standard: IEC 60044-1:2003
Features: low partial discharge, low dielectric loss, high insulation reliability, good sealing performance, horizontal structure which is convenient for transportation.

HV Voltage Transformer (Suspend Production)

Application: used for voltage signal switching of HV no-current line, and provide isolation between the electrical apparatus under repair (like HV busbar, circuit breaker, etc.) and the HV live line. Voltage level: 110kV.
Standard: IEC 60044-2:2003
Features:  
1. Metal expander with pressure relief devices or nitrogen-filled positive pressure sealing structure; 
2. Meeting the national requirements on electrical measurement, ensuring accurate measurement; 
3. High quality support used.
