Transformer parameters meter «Коэффициент-3.1»

Transformer parameters meter «Коэффициент-3.1»



The instrument allows measuring the following parameters for the transformers of all the circuits and groups of connections according to GOST 30830 simultaneously at every phase:
- Transformation rate;
- Effective (root-mean-square) voltage.
“Коэффициент-3.1” is the new version of the “Коэффициент-3” instrument distinguishing with better metrological characteristics and operating speed.
It is manufactured in two hardware versions:
- Standard (operating temperature range: from 5 °C to 40 °C);
- North (operating temperature range: from minus 15 °C to 55 °C).

It has:
- Permanent memory for 200 measurement results;
- Galvanic isolated interface RS232 for the connection to the computer;
- Programmed number of measurement with the indication of the averaged value;
- Manual or automatic measurement ranging.
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.
