RAP parallel coupling

Depending on the requirements the injection method may either be done by parallel coupling (which is today the most common) or by serial coupling. Both types of coupling are suitable for signal injection at medium or high voltage level.

The ripple control signals are injected in parallel to the network supply transformer. The RAP consists of primary capacitors, coupling transformer, tuning and matching equipment on the LV side. The coupling transformer with iron core and air gap ensures excellent transmission characteristics and isolates the MV / HV network from the transmitter output circuit.

  • Low-loss transmission of the audio frequency signals into the network
  • Low losses during transmission pauses due to high Q-factor of coupling transformer
  • Protection of transmitter against influences of the 50/60 Hz power distribution network
  • Isolation of the low-voltage coupling section from the network to be controlled
  • Tuning of the coupling on the LV side by use of tuning capacitors in parallel to the LV winding of the coupling transformer
  • Basic tuning in the factory affords short commissioning time
