Transformation parameters meter "Coefficient 1.3"

The device "Coefficient -1.3" allows to measure sequentially on each phase for transformers of all schemes and connection groups according to GOST 30830:
- transformation ratio;
- no-load losses at low voltage;
- short-circuit resistance.
"Coefficient -1.3" is a new version of the device "Coefficient", characterised by extended functionality, better metrological characteristics and faster performance.
It is produced in two versions:
- standard (operating temperature range from 5?C to 40?C);
- Northern (operating temperature range from minus 15?C to 55?C), has improved construction and moisture protection.
It has:
-non-volatile memory for 700 measurement results;
-galvanically isolated RS232 interface for connection to a computer;
-programmable number of measurements with indication of the average value;
-manual or automatic selection of the measurement limit.
