UHF Drain Valve Sensor – accessory for the MPD 600
The UVS 610 allows partial discharge (PD) measurements to be conducted in liquid-insulated power transformers.
The PD Sensor is inserted into a power transformer through the vent of the oil drain valve. Used with with a UHF converter, the UVS 610 is connected to the MPD 600 measuring system. A useful scale on the slide-rod ensures that the device is correctly inserted into the oil drain valve.
Partial discharge measurements in high frequency ranges are conducted inside the tank of a power transformer. The screening effect of the tank attenuates potential interferences, such as corona discharges. This ensures a more sensitive detection of partial discharges.
- 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
