STARRTONE with CONDIS

Starrtone company is Switzerland CONDIS SA high voltage capacitor products in mainland China only authorized sales agents.

Grading capacitors used in circuit breakers allow the high voltage to be distributed uniformly in the interrupting chambers. Years of experience and know-how in the production of high voltage capacitors makes them suitable for all types of applications in the generation, transportation and distribution of electrical energy. GIS circuit breakers for tough environments with extreme temperature variations, dust, pollution or confined space use grading capacitors. Coupling capacitors for special applications are also available for this type of switchgear substation and transmission.

Capacitors for Generator Circuit Breakers

A generator circuit breaker is a protection device for the transformer and/or generator against short-circuit currents. The operation of generator circuit breakers, located between the generator and the step-up transformer, is associated with extreme stresses due to the conduction and interruption of very large current, both in normal and fault situations. In addition, after interruption…

Grading Capacitors for AC Live Tank Circuit Breaker

In air-insulated switchgears (AIS), Grading Capacitors ensure a uniform distribution of the voltage across the breaking chambers of the Live Tank Circuit Breaker. Grading Capacitors for AIS are compliant with standard IEC 62146-1. They are available with a porcelain or a composite insulator. All standard porcelains are equipped with single or alternating long-short sheds and...

Grading Capacitors for AC Dead Tank and GIS Circuit Breaker

Gas-insulated switchgear (GIS) Circuit Breakers for tough environments with extreme conditions (temperature variations, dust, pollution or confined space) use grading capacitors to ensure a uniform distribution of the voltage across the breaking chambers. CONDIS® GIS Capacitors have a sophisticated design— the electrical insulation is made by a vacuum impregnated epoxy resin tube with a smooth external…

TRV Capacitors for Dead Tank Circuit Breaker

In air-insulated switchgears (AIS), Transient Recovery Voltage (TRV) Capacitors are installed phase-to-ground. They decrease the oscillation frequency and the rate of rise of recovery voltage (RRRV) of TRV, which occurs during initiation or interruption of current flow. TRV Capacitors are thus installed to increase breaking power of the Circuit Breaker. TRV Capacitors for AIS are...
