GlobeCore TOR-80 are automatic portable unit designed for the breakdown voltage testing of transformer oil and other liquid dielectrics according to IEC 60156, VDE 0370, ASTM D877, ASTM D1816, IRAM 2341 as well as according to user procedures defined in the corresponding section of the unit menu. The standards list can be supplemented and modified according to customer requests as well as new versions of the standards become available.
The TOR-80A (TOR-80 ASL) tester feature is an internal rechargeable battery that provides the possibility of autonomous operation in the field at the place of the transformer functioning.
Features
– Automated and accurate measurement of breakdown voltage up to 80 kV.
– Instantaneous (4 μs) disconnection of the test voltage upon breakdown.
