High Voltage Digital Partial Discharge Tester For Power Equipment Insulation Test

Product Description:

HZJF-124 digital partial discharge detector is the newly development digital LCD partial discharge detector for solving the problem of low brightness and short service life of the traditional local discharge detector. It is wildly used in measurement of partial discharge of various HV electrical products such as transformer, mutual inductor, HV switch, switch cabinet, zinc oxide surge arrester, power cable etc.

Product Features:

1. After digital processing,the partial discharge signal is displayed by liquid crystal.
2. Easy operation
3. With multiple display mode like ellipse,line,or sinusoidal.
4. Adopt digital windowing technique to avoid influence of interference to measurement.
5. Arbitrary phase windowing,with selection of single window and double window,ellipse rotating 150 degree.
6. The current discharge map can be stored,static observation and analysis to partial discharge pulse.
7. Can store the current discharge map.
