Motorized Oil Test Set is suitable for testing dielectric strength of insulating oils e.g. transformer oil etc confirming to IS:335 for carrying out test as laid down in IS:6792. The unit consists of High Voltage Transformer with epoxy encapsulated secondary coils. The High Voltage Transformer feeds H.T. through electrodes to the oil under test in a removable oil test Cup with adjustable gap as per IS specifications. The H.T. is varied sleeplessly by varying the primary voltage through a variac. All protective and safety devices viz MCB, pushbuttons, indicators, switch, contractor and electrical interlock etc. are in built in the unit.
