Frequency Injection Transformer


Injection of remote control signals at a frequency other than 50 Hz.

The CAHORS Group works on primary substations by offering wound product solutions designed to communicate via frequency injection. Frequency injection transformers inject remote control signals at various frequencies (175 Hz or 188 Hz for the French markets) on HVA networks (ex. 15 kV or 20 kV), in HVB/HVA power substations.
