Static automatic capacitor banks with rejection filters (tirystors maneuver)
FRE
Cod: FRE
Description
The FRE Series capacitor banks with detuned filters have been designed for power compensation purposes in networks with fluctuating load levels, a high content of harmonics and where there is a risk of resonance. Power variations are relatively quick (in milliseconds) so that the switching operations can be carried out by thyristors, which are connected to a voltage control plate; the capacitor is connected and disconnected with a zero voltage difference. This system avoids transients in the connection and disconnection of steps, with an immediate response to load fluctuations.
