The high Voltage also known as di-electric withstand tester comes with customized facilities like voltage rampup rate zero interlock, Plus the user may specify the voltage level and leakage milliampere level so as to suit its testing needs.
a) Zero Interlocksb) Shrouded type push button for H.T. ONc) H.V. Transformer Epoxy moulded Air Cooled mounted on seperate trolley
a) High Voltage and leakage current on separate metersb) “HT OFF/FAULT/HT ON” indications on lampc) Provision for push button for H.V. ON and Emergency OFFd) Panel will be castor mounted & built in extruded alluminium for better aesthetics

PLC Programmable Unit will have facility to carryout test
a) In Manual Mode sudden application of Test Voltageb) In Auto Mode (Programmable Mode) prescribed in D149-09 (Clause 12 procedure) i.e. Method A – Apply Voltage uniformly to the test electrodes from zero at one of the rates until breakdown occurs.c) In Auto Mode (Programmable Mode) prescribed in D149-09 (Clause 12 procedure) i.e. Method B.d) In Auto Mode (Programmable Mode) prescribed in D149-09 (Clause 12 procedure) i.e. Method C.e) HMI on PLC for different parameters & process.
Other than those mentioned above, the kilovolt and mA level can be custom-made. In case of routine testing solution employing mechanical test jigs, the number of MCBs (to be tested simultaneously) can be customized as 1, 4 and 20.
The test bench tests the di-electric withstand capability of the product with settable high voltage and allowable leakage current
