Read more Regulator for Petersen coils, REG-DP(A)
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. Key features and benefits: System solutions for networks with isolated or deaf-grounded neutrals. Fine tuning of Petersen coils. Reliable determination of earth faults. Definition of repeating and short circuits. The function of recording closures. Remote connection with devices. Compliance with the following standards and recommendations: IEC1010 / EN61010 (VDE 0411), CAN / CSA - C 22.2 No. 1010.1- 92, VDE 0110, IEC 255-4, EN 55011: 1991, EN 50082-2: 1995, IEC 688-1, IEC 529, EN 50178 / VDE 0160 / 11.94, VDE0106 part 100, DIN40050.
