Audited Supplier Transformer Turn Ratio Meter Turns Ratio Tester TTR Testing Equipment
Why is transformer turn ratio (TTR) test necessary?
Power transformer turns ratio test is an AC low voltage test which determines the ratio of the high voltage winding to all other windings at no-load. The turns ratio test is performed on all taps of every winding.
The purpose is to check whether the number of turns of each winding, the assembly of lead wires, and the indication position of the tap changer meet the requirements.
The parallel operation of small and medium-sized transformers with a ratio difference of 1% will generate a circulating current of 10% of the rated current in the transformer windings, which will greatly increase the loss of the transformer and be detrimental to the operation of the transformer.
Features:
* GDBC-901 Three Phase Transformer Turns Ratio TTR Measuring Meter is designed according IEC76-1, IEC60044 and GB/T1094.
* The tester makes automatic measurement with no need to set any parameters and automatically completes the three-phase ratio and connection group measurements with easy operation.
* The tester measures three-phase and single-phase transformer ratios automatically, and calculates the ratio error.
* The tester can measure transformer connection group label and polarity to clearly display the first and second winding connection vector.
* GDBC series Transformer Turns Ratio TTR Meter is a professional testing equipment which is suitable for transformer manufacture, transformer service industry, substation maintenance, power transformer /distribution transformer maintenance company and other transformer testing field.
