This HV Tester is unique in the fact that it is provided with an indigenously designed fixture to RCCB with the facility to test the di electric strength between:
Test 1:- HV apply across terminals
Test 2:- HV apply between terminals of adjacent poles.
Test 3: HV apply between terminals of all poles and enclosures.
Safety Features: a) Zero Interlock b) Epoxy cast Transformer
Zero Interlock bypass facility, timer bypass facility.
Input Supply : 230 V AC, +/- 10 %, 50 Hz.
Test Voltage : 0 – 3 KV AC.
Tripping : 200 mA.
Time Setting : 0 - 60 Sec.
Safety Features : Fixture Cover Interlock Epoxy cast Transformer
Lamp Indication : HT ON, OK, NOT OK (fault), Test Over,Test 1, Test 2, Test 3, Low Voltage, Low Current
Fuse : 3 A AND 5 A current ratings.
The test is conducted to asses the dielectric withstand capacity of an RCCB for various insulation paths - between the body and trminals, adjacent terminals and opposite terminals, etc. The settable maximum allowable leakage current allows the user to compare RCCB prototypes and subject the RCCB to harsher conditions than in real world.
