Product Details

The Megger 550005B Single-Phase, Hand-Cranked TTR Transformer Turns Ratio Test Set measures the turns ratio and exciting current of windings in power, potential and current transformers. Deviations in turns ratio readings indicate problems in one or both windings or the magnetic core circuit.

 

The Megger 550005B Single-Phase, Hand-Crank Transformer Turns Ratio Test Set aids in identifying:

  • Shorted coils
  • Open circuits
  • Incorrect connections
  • Internal faults or tap-changer defects in step regulators as well as in transformers

 

The Megger 550005B measures highly sensitive turns ratios of up to 129.99:1 with accuracy of +/- 0.1%, and operates on the principle that the voltage ratio of the transformer at no load is practically equal to the true turns ratio.
