Raytech WR50-12 and WR14 Offer Winding Resistance Testing at its Best

  • Uncategorized

Low resistance ohmmeters and winding resistance test sets, at first glance, might appear very similar. Both sets are used to measure very low resistances using an applied DC current , but that is where the similarity ends.  Low resistance ohmmeters are well suited for a wide range of applications where measuring the integrity of a connection or bond is required.  In these applications there is no storage of energy in the test specimen.  When looking at the windings of a motor or transformer keep in mind that these windings are essentially large inductors.  The higher the voltage and the larger the (MVA) capacity, the higher the induction and hence a potential hazard when applying DC test current.  Standard low resistance ohmmeters simply do not provide the added safety features offered in a dedicated winding resistance test set such as the Raytech models WR50-12 and WR14 units. 

Raytech WR50-12 Two Channel Winding Resistance Test SetRaytech WR50-12 Two Channel Winding Resistance Test Set is designed for a high degree of accuracy for the measurement of very low resistance of inductive loads.

Raytech WR14 15 Amp Winding Resistance MeterThe Raytech WR14 15 Amp Winding Resistance Meter is a battery or line-operated, field-portable instrument designed specifically to measure the dc resistance of all types of magnetic windings safely and accurately.
