Transformation Parameter Meter "Coefficient 3.3" for Measuring Transformer Parameters

The device "Coefficient-3.3 allows to measure simultaneously for three phases for transformers of all schemes and connection groups according to GOST 30830: -transformation ratio; -no-load losses at low voltage; -short-circuit resistance; -voltage and current; <ul> <li>- power factor;</li> <li>frequency of the measured voltage (current)</li> <li>phase angle between voltage and current.</li> </ul>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),</li> </ul>has improved construction and moisture resistance. It has: <ul> <li>- manual or automatic selection of measurement limit;</li> <li>programmable number of measurements with indication of the average value;</li> <li>non-volatile memory for 200 measurement results;</li> <li>galvanically isolated RS232 interface for connection to a computer.</li> </ul>.
