The WR14 is a Winding Resistance meter system specially designed for high precision DC winding resistance measurement of high inductive windings such as large power transformer windings. It can also be used for precisely diagnosing and for preventive maintenance. Many power transformer’s faults such as shorted turns, tap changer problems and loose connections can be detected precisely. For maximum mobility, the WR14 is battery operated and very lightweight. It includes also special tools such as advanced transformer core demagnetizing, temperature rise measurement and analysis (optional), and automatic temperature correction using up to 2 temperature probes. The WR14 can inject current to both high voltage and low voltage side using the jumper cable provided, and resistance measurement can be performed simultaneously using two separate measurement channels.memory, can be transferred to the Raytech t-base pro software or simply can be printed by using the built-in thermal printer.
