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.

The set of 6 input measurement cables with the crocodile clips (8 hardware versions) that differ with the length and cable (tube) insulating material, is additionally supplied against the customer’s order.
