The device allows to measure simultaneously on three phases for transformers of all schemes and connection groups according to GOST 30830:
- transformation ratio;
- effective (RMS) voltage simultaneously on three phases.
"Coefficient-3.1" is a new version of the device "Coefficient-3", which is characterised by 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.
Has:
- non-volatile memory for 200 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.
