High Accuracy Strong Safety Dc Hipot Tester For Measure Hv Cables /
Surge Arresters
1. Product Name:
DC hipot tester ZGF
2. Equipment Description:
Portable DC hipot tester is important equipment for DC voltage
withstand test and leakage current test of HV electrical
equipments, cables, surge arresters in maintain service of
electrical production, transmission and consumption departments.
The tester has a good performance in stability and protection of
faulty specimen breakdown. The separate units of tester make the
operator keep enough safe distance with high voltage circuit.
3. Product Features:
The main advantages of ZGF could be described as follow:
High accuracy and reliability
Small size and light weight
High voltage booster has strong mechanical performance and high
insulation ability.
Application of the tester is safety enough.
Protection circuit avoid the wrong operation of tester.
The leakage current at HV side is measured by digital micro ampere
meter. The maximum error of meter can be assured is not more than
1uA.
4. Technical Parameters:
1. Power: AC220V+10%, 50Hz+1%
2. Output high voltage indicator error: <1%Readings+1D
3. Output current indicator error: <1%Readings+1D
4. Ripple contain factor of high voltage: <0.5%
Readings+0.05%Full scale
5. 0.75 times output voltage indicator error: <1% Setting value,
can be locked
The model of ZGF is defined as ZGF Max voltage / Max current. Such
as ZGF 200kv/2mA stand for the maximum voltage output is 200kv and
the maximum current is 2mA
