Oil Dielectric Test Sets KEP-UIM-90MC
An oil breakdown voltage tester UIM-90MC is designed for determining the breakdown voltage of the transformer oil and other liquid dielectrics in accordance with GOST 6581-75, and most other international and national standards (rate volatge rise, agitation algorithm, the shape of the electrodes and the distance between them).
The divice can store up to 200 last measurements and has the ability to save the results to a computer.
UIM-90MC can operate in both manual and fully automatic modes.
In the fully automatic mode, UIM-90MC can perform the following:
- The time delay between trials (first and subsequent);
- Mixing samples of the dielectric;
- Calculation of the average breakdown voltage and the coefficient of variation;
- Signaling upon completion of the work;
- Printing a report on the built-in printer.
The unit features both Russian and English interface menu languages.
