Product Details

Introduction:

This Transformer No Load Test Equipment is designed for transformer capacity, load loss and no load loss testing.

It can measure following parameters of transformer: capacity, transformer type, no-load current, no-load loss, short circuit (load) loss and impedance voltage.

The Transformer No Load Test Equipment is reliable, accurate, simple for wiring and operation.

 

Features:

  • Measurement range of voltage, current and capacity is wide, and measurement range can convert automatically. For example, the instrument can complete load test under full current of distribution transformer below 1000kVA. The load test of distribution transformers below 3150kV can be completed under 1/3 of the rated current (under 1/3 rated current, the instrument can be converted to the load loss parameter under the rated current).

  • When testing load and no load loss of three phase transformer, it can automatically determine whether the wiring is correct or not, and display vector of three phase voltage and current.

  • All test results of Transformer No Load Test Equipment can be automatically corrected.

  • LCD 20 * 240 large screen.

  • Users can preset 40 sets sample parameters, and these parameters can be deleted or added at any time.

  • With real-time electronic clock, This Transformer No Load Test Equipment can automatically record test date and time.

  • 500 sets test data can be stored in the tester, meanwhile, users can connect the tester with computer to upload the data.

  • Transformer No Load Test Equipment has built-in printer, users can print test result immediately after test.

  • Allows external current transformers or voltage transformers to extend measurement range, so it can test any kinds of transformers.
