High Voltage Instrument Transformers
Available from 25 kV to 800 kV for the voltage or current measurement, protection and control.
Current Transformers, Inductive Voltage Transformers, Capacitive Voltage Transformers, Combined Current/Voltage Transformers and Station Service Voltage Transformers are designed to transform high current and high voltage levels down to low current and low voltage outputs in a known and accurate proportion specified by the product nameplate ratios. All units are tailored for specific applications, either to operate accurately at steady state conditions or to maintain reasonable accuracy reading up to extreme fault level conditions.
These products consist of high dielectric strength oil-filled designs using paper and foil shields impregnated with refined dehydrated and degassed transformer oil, or stress-controlled, shield-graded SF6 gas-insulated designs. This ensures conservative reliable performance for decades of service in demanding global outdoor environments.
