How close do you have to be to use a UHF Directional Antenna to detect Partial Discharge (PD)?
When using our UHF Directional Antenna, the user can detect PD from hundreds of metres away when at a very high gain setting (higher gain = higher sensitivity) and in a UHF quiet environment. The trick is to be able to then triangulate which HV asset is discharging, and discounting other nearby assets. This is performed by lowering the gain (making the antenna less sensitive) and walking toward the asset.
Learn more about how the UHF Directional Antenna can be used together with the UltraTEV Plus² - to enhance the detection of PD activity in open terminal switchyards. See the Sensors tab on our UltraTEV Plus² page.
