Electronic Combined Voltage and Current Transformer

REVCT35-1000 Series
35 kV – 1000 kV

Electronic Combined Voltage and Current Transformer REVCT35-1000 Series
35 kV – 1000 kV by RHM International

HV DryShield® insulated
RHM International: The Innovator in High Voltage Dry type Technologies

Our patented REVCT35-1000 kV electronic combined voltage and current transformer was developed based on our HV DryShield® current transformer technology. The fundamental difference from other electronic instrument transformers in the market is that the collector (Rogowski Coil/voltage divider) and the electro-optical converter are at earth potential. By installing these devices at earth potential the problems of electromagnetic interference, instability and power supply are easily solved and maintenance is more convenient. In summary this electronic combined voltage and current transformer uses a simple construction to deliver accurate, stable, safe and reliable operation with a lower cost-performance ratio.
