TOR-80A (TOR-80 ASL) Transformer Oils Breakdown Voltage Tester with Battery
TOR-80A (TOR-80 ASL) Transformer Oils Breakdown Voltage Tester with Battery
80 kV | Breakdown voltage | Battery | Compact
The TOR-80A (TOR-80 ASL) tester is designed for assay transformer oil by measuring the electrical breakthrough voltage. The electrical breakthrough voltage is measured in accordance with IEC 60156, VDE 0370, ASTM D877, ASTM D1816, IRAM 2341. This list of standards can be modified and expanded according to the customers’ wishes and to the development of standards’ new versions.
The TOR-80A (TOR-80 ASL) tester feature is an internal rechargable battery that provides the possibility of autonomous operation in the field at the place of the transformer functioning.
Testing procedure
The start screen appears on the display after filling the measuring cell with oil and switching the device on. The operator selects the type of oil and the procedure of testing. TOR-80A starts testing automatically. The result totals are displayed after the last test cycle breakthrough. If needed result totals can be transferred for printer directly from the tester.
