Hungarian compensation capacitor

What are the types of compensation capacitors?

Compensation capacitors are divided into two type families (A and B) in accordance with IEC 61048 A2. • Type A capacitors are defined as: "Self-healing parallel capacitors; without an (overpressure) break-action mechanism in the event of failure". They are referred to as unsecured capacitors.

What is a multicond UHPC power capacitor?

A construction diagram is shown on page 35. multicond-UHPC power capacitors stand out through their combined safety concept with a self-restoring efect and 3-phase internal overpressure disconnector. In low voltage networks, inadmissibly high voltage peaks of up to 3 times the rated voltage can occur through switching operations.

What happens if a capacitor peaks 3 times rated voltage?

In low voltage networks, inadmissibly high voltage peaks of up to 3 times the rated voltage can occur through switching operations. If these loads lead to flashovers in the dielectric, the self-restoring efect is triggered. The capacitor remains fully functional as this happens.

What is the failure rate of a vs capacitor?

VS capacitors are designed for continuous operation at the specified nominal voltage and temperature, whereby IEC 61048 A2 provides for a permissible failure rate of 3% over the capacitor's service lifetime of 30,000 hours. Exceeding either the nominal voltage or temperature will shorten the capacitor's service life.

What are vs MKP capacitors?

VS MKP capacitors feature a self-healing dielectric. In the event of a dielectric break- down in the coil (short circuit), the metal coating vaporises around the breakdown site owing to the high temperature of the transient arc that is produced.
