Model NO.: HZJF-124
Test Voltmeter Accuracy: Better ThanÂ±5%(with Full Scale)
Specification: ISO9001, ISO14001, OHSAS18001
Origin: Hubei, China
HS Code: 9031499090I. Product Information:
HZJF-124 digital partial discharge detector is theÂ newly development digital LCD partial discharge detector for solvingÂ the problem of low brightness and short service life of the traditional local discharge detector.Â It is wildly used in measurement of partial discharge of various HV electrical products such as transformer, mutual inductor,Â HV switch,Â switch cabinet,Â zinc oxide surge arrester,Â power cable etc.
Product Â Features:
1.After digital processing,the partial discharge signal is displayed by liquid crystal.
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 toÂ partial discharge pulse.
7.Can store the current discharge map.
Main Technical Parameters:
1,Capacitance Range of tested products 6PF--250Î¼F
2,Detection sensitivity(See table 1)
