The oil insulation test kit is intended to be used for testing of dielectric strength of insulating oil used in Transformer , Circuit breaker, CTs, PTs etc.
The test kit is fully automatic and has the facility for Auto/Manual selections. The operator simply needs the sample in the test vessel & selects the required test. Testing can be done as per many international ( IEC & European standards ) which are programmed into the instrument memory . Stand time, Stir times & Rate of rise of applied voltage can be selected in Custom Mode also , one set of such selected mode can also be stored in the memory.
In addition to the above set can also perform withstand test(proof) tests. In this test the set allows the set voltage to pre-set value & hold for one minute to see if breakdown occurs. The backlit LCD is used for user friendly operations during the test process. It also display fault condition messages such as open ground and cover open .
All the user selected programmes are chosen through(4x3) key pad. The test results can be printed along with with test type, date, time, breakdown test voltage, averages and deviations. Voltage value can be measured & printed with a resolution of 0.1kV. In reprint option it is possible to have number of printouts for the last test. For each test the readings are recorded and stored in memory.
All stored readings can be transferred via the RS-232 interface to PC. A safety interlock prevents access to the high voltage terminals during testing. The design ensures a high level of safety for the operator. The high voltage chamber is covered by a polycarbonate door.
