100-tov-rus

The instrument “КОЭФФИЦИЕНТ-1.1” allows measuring the following parameters for the transformers of all the circuits and groups of connections according to GOST 30830 consequently at every phase:
- Transformation rate;
- Effective (root-mean-square) voltage.
It is manufactured in two hardware versions:
- Standard (operating temperature range: from 5 °C to 40 °C);
- North (operating temperature range: from minus 20 °C to 45 °C).

It has:
- Manual or automatic measurement ranging;
- Permanent memory for 700 measurement results;
- Galvanic isolated interface RS232 for the connection to the computer;
- Programmed number of measurement with the indication of the averaged value.
The instrument is registered in the State Register of the Measuring Instruments of RF. The measuring instruments type approval certificate RU.C.34.033.A. No. 55541.
