The petersen coil regulator in an IP54 housing
REG-DPA
Petersen coil regulator
REG-DPA
The freely programmable REG-DPA regulator is used in medium and high-voltage networks to regulate continuous, variable-under-load arc suppression coils (Petersen coils, also known as P-coils or E-coils). In addition, they can handle all other control, measurement and regulation tasks having to do with petersen coils. The IP54-class device is available for wall mounting, insertion in a control cabinet or in a housing designed for rail assembly.

A diverse range of functions
When this petersen coil regulator was designed, the focus was on a wide range of applications. Correspondingly, the regulator has been equipped with a large number of functions. The device can handle numerous tasks:
- Reliable regulation of the petersen / arc suppression coils
- Logbook and recorder
- Regulator statistics display
- Umin and Umax monitoring function
- Automatic resistor control
- Parallel regulation with and without communication between the regulators
- Freely programmable parameters for binary inputs and outputs, analogue channels and free combination of signals (UserBAFs)
Reliable regulation in case of earth faults
During an earth fault, the petersen coil regulator can correct the coil by a certain amount and thus, say, adjust the network to the resonance or shut it down.
The right control connections for every application
The REG-DPA petersen coil regulator regulator can be connected via REG-P, REG-PE or REG-PED SV control units. The following protocols are available (further protocols on request):
- IEC 60870-5-101 / 103 / 104
- IEC 61850
- DNP 61850
- DNP 3.0 RTU / DNP 3.0 TCP
- MODBUS RTU / MODBUS TCP
- SPABUS
Freely programmable for customer-specific adaptation
Thanks to our long years of experience, we know that each customer and every project will make different demands of the arc suppression coil. That is why we designed the petersen coil regulator REG-DPA so that it could be freely programmed to meet these demands and achieve the special tasks assigned to it.
Current injection as an aid to successfully attune the petersen coil
The classic regulation process, i.e. searching for the resonance curve across the range of travel of the coil, can no longer successfully adjust the petersen coil in certain network situations.
We have developed this current injection for the frequent cases where the zero-sequence voltage is highly disturbed or subject to extreme influences or where networks are highly symmetrical. The current injection creates a signal that is fed into the network via the auxiliary power winding of the petersen coil. From the network reaction, the REG-DPA is able to calculate a resonance curve.
