Transformer Parameter Measurement Device "Coefficient 1.3" for Efficiency Analysis

The device "Coefficient -1.3" allows to measure sequentially on each phase for transformers of all schemes and connection groups according to GOST 30830: <ul> <li>- transformation ratio;</li> <li>no-load losses at low voltage;</li> <li>short-circuit resistance.</li> </ul>"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: <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>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.
