Fully Automatic Transformer Winding Resistance Tester
Measure DC resistance of transformers windings etc. Introduction: The NMC ''TDR'' is a high precision, new generation, light weight large output current and micro-processor controlled tester. This replaces old DC wheat stone bridge and double arm bridge for measurement of DC resistance. ''TDR'' adopts new advanced test current power supply technology, four terminal measurement, digital display of resistance value and test current. ''TDR'' is powered by 220V AC mains single phase supply. The measurements are accurate as the test current is highly stable. High automation is achieved with automatic discharge warning.Principle: The constant current generated is fed to the resistance under test through the current terminals and the voltage drop across the resistance under test is measured and displayed in ohms. A true four terminal measurement is used to eliminate the need for lead resistance compensation.

Wind Turbine Condition Monitoring
It has also become increasingly apparent in recent years that the wind turbine industry has recognised the importance of condition-based monitoring, especially for offshore wind turbines, where access is often limited.To increase reliability and minimise down time, many wind turbine manufacturers, owners and operators are turning to condition-based monitoring systems, aimed at predicting wind turbine maintenance issues, so that operators can quickly and effectively carry out predictive maintenance, repairs and replacements of components when needed, without the need for costly routine maintenance checks and visits. As a result, a condition monitoring system increases operational time, improves site performance and reduces maintenance costs for wind turbines, especially offshore ones.

Impulse Cable Tracer
Wayfind'r
The WAYFIND'R Impulse Cable Tracer was originally designed for electric utility use to accurately identify the route of buried secondary cables. Because the WAYFIND'R imposes an audio frequency signal on the cable, the signal is not induced into adjacent cables or pipes, eliminating false signals. The WAYFIND'R may also be used fro tracing indoor wiring and buried shielded primary cables.
