Voltage regulator for Petersen coils
a. eberle
Application
In medium- and high voltage networks, the free programmable regulator REG-DP is used for the automatic control of Petersen coils (P-coils), which are continuously adjustable on load. Furthermore, the controller can solve a lot of control-, measuring- and recording tasks all around the Petersen coil.
Control methods
As a standard feature, the regulator offers different methods for the automatic control of a Petersen coil. Depending on the requirements, the REG-DP can control either to a percentage or absolute detuning-current or a given zero-sequence-voltage. It is remarkable, that during a ground-fault, the Petersen coil can be corrected by the detuning and adjusted to the resonance point. Furthermore, there are different methods available for the control of several Petersen coils in the same network.
