Distribution network application recommendation
The tolerance boundary for a distribution network with a voltage level of 400 V may be ±10 %. In this case, the voltage of 430 V is commonly measured in the distribution networks. This effect may be caused by the usage of non-linear devices (generation of higher harmonics), low short-circuit power of voltage sources (voltage fluctuation), etc.
We recommend using capacitors with higher nominal voltage than the nominal voltage of the distribution network. In a 400 V distribution network, we recommend capacitors with a nominal voltage of 440 V and capacitors with a nominal voltage of 480 V for detuned power factor correction with reactors.



Application power capacitors

Power capacitors are intended for individual, group or central power factor correction. To compensate inductive reactive power of industrial appliances such as electric motors, welding equipments, etc. This inductive power is undesirable for the grid provider and shall be avoided with power factor compensation.

Construction power capacitors

Power capacitors are produced in MKP system. It means metallized polypropylene with self-healing properties and extremely low dielectric losses.

Capacitors are filled either with inert gas (N2) for CSADG types or semi solid resin for CSADP types. The resin is non-toxic and ecologically friendly.

Three phase capacitors have three elements connected in delta. Capacitors are protected with overpressure disconnector, which ensures safe disconnection of the capacitor from the network in the event of overloading or at the end of its operation life. All the capacitors are equipped with built-in discharge resistors.

The case of the capacitor is protected against bursting by the overpressure disconnector. Its proper function is ensured only if the specifications and conditions (voltage, current, temperature, correct installation, maintenance) are observed. Failure to meet and/or exceed these conditions may result in bursting of the capacitor case or even explosion and subsequent fire.
