Frequency Injection Transformer
A CAHORS solution for injecting 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, for infrastructures and transport. 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.
