Application
High voltage capacitor reactive power compensation equipment can improve power factor and eliminate harmonic current, which is widely applied to low power factor and big harmonic current and unsteady high voltage power grid system. In the electric power, paper making, chemical industry, construction materials and textile industry, this equipment has a widespread use in frequency conversion equipment, soft starter, uninterruptible power supply and other electrical equipment.

Technical parameter
Voltage rating: 6Kv, 10Kv
Frequency: 50Hz
The loss tangent value: <0.0005
Insulation level: 32/60KV，42/75KV
Maximum allowable current: 1.3 times of root-mean-square value of current
Total capacitance tolerance: 0-5%
Power off protection: there is discharge resistance in the capacitor. After power off, the voltage of terminals will decrease from 2Un to less than 75V in 10min.

We provide customized service of high voltage capacitor reactive power compensation equipment according to the requirement of customers.

Service condition
1. This type of high voltage capacitor reactive power compensation equipment is commonly installed indoors and extra protection facilities is needed when installed outdoors.
2. Altitude of installation sites is less than 2000m.
3. There is no strong mechanical vibration on the surroundings.
4. Installation area should be away from flammable and explosive products.

Switching overvoltage
The residual voltage of capacitor cannot exceed 10% of rated voltage before operating. Besides, the first peak of voltage cannot exceed 2√2 times of transition voltage when switching capacitor with breakers. In this condition, our capacitor can switching 1000 times annually and related critical current peak can be up to 100IN. When switching capacitor frequently, duration and amplitude of over-voltage and over-current should be in lower level.

All automatic control switching compensator capacity are combination of available above the known capacity or in the vicinity of the weighted combination and a control cabinet (900X1500X2500) series reactance rate is determined according to the harmonic content in the system, such as the need to more than 3 times harmonic suppression, K selected 12%, for 5 times or more harmonic suppression, K selected 6%, or according to the design department of electric power requirements of the decision.
