100KV / 100 mA

The primary application of this hi-pot is to test systems which handle medium voltages. Distribution transformers, SF6 circuit breakers, oil vacuum circuit breakers as well as medium voltage switches and wind generators (during lightning) typically handle high voltages like 70 to 100 kV. These devices can be tested on this hi-pot testers.

This equipment is available in multi-tester configuration wherein hipot testing can be clubbed with other test modules such as current injection, continuity testing, milli-volt drop and micro ohm measurement plus other go / no go parameters making it an ideal instrument to be integrated on production floors.

Other safety features include transparent enclosures, zero interlock facility, door close interlock for operator safety.

Optional PC interface module connects the hipot tester with PC based Testware for data logging and stand alone operation and thus, test reports can be generated in a customized format.

The burnout feature ensures pin pointing of the fault location, a key feature for testing engineers on the factory floors as well as Research and Development Engineers involved in insulation design of industrial motors and transformers. This feature points out the weakest point in the system.

SCR ELEKTRONIKS 100 kV high voltage tester (model: PHVT 100 ) offers you a wide range of test voltages merged with features like burnout, ramp, and pre-programmable test voltage with a universal high voltage testing range of 5 – 100 kV with selectable tripping threshold. This makes the tester an ideal solution for customers seeking an expanded high voltage testing capabilities covering a wide range of applications.

Application and Benefits:

The primary application of this hi-pot is to test systems which handle medium voltages. Distribution transformers, SF6 circuit breakers, oil vacuum circuit breakers as well as medium voltage switches and wind generators (during lightning) typically handle high voltages like 70 to 100 kV. These devices can be tested on this hi-pot testers.

The ramp enables the user to program dV / dt as per the application desired in addition to pre programming the test voltage and test time. Digital meter displays indicate easy readability of test results.

In addition, the user may opt for a host of customizable features (given below) to suit their unique requirement.

Pneumatic test jigs & programmable controller are optional modules to mount & hold the device under test and to automate the test process. Most hipot tests are carried out between different points on the device under test in sequence. Hence the jigs along with the programmable controller facilitate automatic sequencing of hipot test & expedite the test procedure.
