Description
The Motwane make XWRM-10 is a dual channel, 10A rated, Transformer Winding Resistance Meter designed and developed after extensive research on challenges and requirements of testing of various Transformer winding resistance. The instrument has One Current channel and two resistance Channels. The instrument provides a large open circuit voltage of 42Volts, for fast charging of the highly inductive windings of transformers, to provide stable resistance values in minimum time. The XWRM-10 is intended to replace complex bridge set up with a single compact instrument. The XWRM-10 is based on 4-wire measurement method to measure low resistance accurately. The instrument is well protected against inductive kickbacks offered by the inductive windings and gives stable reading on various types of transformers. The XWRM-10 is user friendly and easy to operate. The test information is displayed along with real time data on large LCD display with backlit during TEST ON condition. The test cables are provided with specially designed industrial grade heavy duty crocodile clips for better grip and durable performance in harsh conditions. The instrument and the accessories come in trolley mounted heavy duty casings for easy transportation on the fields. Frequent testing of Transformers for winding resistances can yield huge revenue savings, because small increase of winding resistance, leads to huge full load losses.
