Transformer Parameter Measurement Device "Coefficient 3.1" for Accurate Measurements

The device allows to measure simultaneously on three phases for transformers of all schemes and connection groups according to GOST 30830: <ul> <li>- transformation ratio;</li> <li>effective (RMS) voltage simultaneously on three phases.</li> </ul>"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: <ul> <li>- standard (operating temperature range from 5?C to 40?C);</li> <li>Northern (operating temperature range from minus 15?C to 55?C), has improved construction and moisture protection.</li> </ul>Has: <ul> <li>- non-volatile memory for 200 measurement results;</li> <li>galvanically isolated RS232 interface for connection to a computer;</li> <li>programmable number of measurements with indication of the average value;</li> <li>manual or automatic selection of the measurement limit.</li> </ul>.
