Power Capacitors
High Voltage Capacitors
Description
High-voltage cosine capacitors are used as part of UKRM, filter compensating units, banks of static capacitors, etc. They are used to increase the electrical power of 50 Hz AC installations. They contain built-in fuses and discharge resistors that reduce the voltage at the terminals of the cosine capacitor.
