KPM TWRT YY

The DC resistance measurement of transformers is a critical quality control and diagnostic test. It is required during various stages, including semi-finished product testing, final product verification, pre-delivery inspection, installation commissioning, handover testing, and routine preventive maintenance.
This test helps identify manufacturing defects such as improper material selection, poor welding, loose connections, or broken wires within the transformer coil. It also detects potential operational risks that may not be evident during normal functioning.
The KPM TWRT YY Automatic Transformer DC Resistance Tester is a high-speed, reliable testing instrument designed for measuring the DC resistance of power transformers, instrument transformers, generator windings, and motor windings.

Features:
All DC resistance data for high and low voltage winding can be measured with connection for only one time.

For transformer with neutral point, its three phases can be measured at the same time, with great time saving.

For three-phase, five-column, delta-connected transformer, its low-voltage winding can be measured through magnetization method with fast speeds.

The instrument has the function of demagnetization, which can eliminate the residual magnetism at one time.

Wide resistance measurement range and high resolution, with multiple current steps to choose from.

Sophisticated back-EMF protection.

The longitudinal testing of DC resistance of on-load regulating transformers can be done in a single pass.

Highly accuracy as well as anti-interference, shockproof and easy to carry features.

Easy operation with a 5.0" 65K colour touch screen.

Built-in high-capacity non-volatile memory for 500 sets of data.

Built-in high-speed micro thermal printer for printing measurement data.

Built-in high-precision clock for real-time time display.

USB storage function available.
