Transformer Oils Breakdown Voltage Tester TOR-80A (TOR-80 ASL) with battery
The TOR-80A (TOR-80 ASL) tester is specifically designed for assessing transformer oil and other liquid dielectrics by determining their electrical breakdown voltage. This breakthrough voltage measurement adheres to standards such as IEC 60156, VDE 0370, ASTM D877, ASTM D1816, and IRAM 2341. It’s worth noting that this list of standards can be adjusted and expanded to align with customer preferences and evolving standards.
One notable feature of the TOR-80A (TOR-80 ASL) tester is its built-in rechargeable battery, enabling autonomous operation in the field where transformers are in use.
Testing Procedure
Upon filling the measuring cell with oil and switching on the device, the start screen appears on the display. The operator then selects the oil type and the testing procedure. TOR-80A initiates the testing process automatically. The cumulative results are presented on the display following the completion of the last test cycle breakthrough. If necessary, these result summaries can be directly transferred to a printer from the tester.
