Ultra High Frequency (UHF)

IPEC’s UHF (Ultra High Frequency) sensors are used to detect PD in EHV cable terminations, GIS (Gas Insulated Switchgear). The sensors pick up signals in the UHF range (200MHz-2.5GHz) and are mounted against the insulating barrier spacers that separate components of the HV asset. The sensors work with multiple IPEC monitoring systems.

Sensors are installed differently depending on the asset manufacturer and model and accessibility to insulating sections, gaskets, UHF windows, and accessibility. Please contact IPEC for specific applications
