What is the Transformer Turns Ratio (TTR) test?

Transformer turns ratio (TTR) tester manufactured by Lucyelec Test Equipment Co., Ltd. can verify the operating principle of a power transformer and identify any shorted turns or open-circuited conditions. A transformer functions with a primary winding, or coil, sending an alternating current (AC) to a secondary winding. The process creates a mutual induction with voltage and current varying based on the number of turns on each winding. The ratio of turns on a primary winding compared to the turns on a secondary winding is the transformer turns ratio.

The TTR tester applies a low voltage to the primary winding, then records the voltage that comes from the secondary winding. That voltage from the secondary winding can determine if the transformer is working correctly or any possible issues with the equipment and its turns ratio.

The TTR test offers a safe and simple way to ensure that expensive transformers work correctly. A transformer should maintain a turn ratio within 0.5% of the nameplate specifications. TTR test results outside that range can reveal problems with the transformer that could get worse or more expensive down the line.

TTR test results can reveal many common transformer faults, including the following issues:

• Shorted Turns

• Phase-to-Phase Short

• Open or Burned Windings

• Turn-to-Turn Faults

• Magnetic Core Saturation

• Insulation Breakdown
