Measure partial discharge in liquid-filled power transformers

The UVS 610 allows partial discharge (PD) measurements to be conducted in UHF ranges with great sensitivity from inside the tank of liquid-insulated power transformers. The UVS 610 PD sensor is inserted into a power transformer through the vent of the oil drain valve. Used with a UHF converter, the UVS 610 is connected to a compatible PD measurement system. A useful scale on the slide-rod ensures that the device is correctly inserted into the oil drain valve.

Key features

• Partial discharge measurement is possible in the UHF frequency range
• Compatible with both DN 50 and DN 80 valves
• Offers a trigger signal for acoustic PD measurements
• A system sensitivity check is available using the UPG 620 pulse generator accessory

Applications

• PD detection inside liquid-filled power transformers with oil flanges
• Triggering of acoustic PD measurements used in PD localization
