Midel 7131 transformer oil breakdown voltage tester TOR-80

Midel 7131 transformer oil breakdown voltage tester TOR-80

To precisely assess the dielectric strength of synthetic transformer fluids like the MIDEL 7131, Globecore created the Midel 7131 transformer oil breakdown voltage tester TOR-80. In order to ensure the dependable operation of transformers and to monitor the state of insulating fluids, this device is essential. The TOR-80 makes it possible to quickly and precisely calculate the oil’s breakdown voltage, which aids in detecting the presence of impurities or moisture that may weaken the insulating qualities. Stable and reproducible results are guaranteed, and it conforms with international standards. Substations, service centers, and laboratories are the best places to use it. For professionals of all skill levels, the TOR-80 is a universal solution due to its small size and simplicity of use.
