BZC type transformer automatic ratio group tester

Overview:

In the production process of semi-finished and finished power transformers, before the installed transformers are put into operation and during the operation of transformers in the power system, according to the preventive testing regulations of the Ministry of Electric Power, it is required to regularly conduct turns ratio or voltage ratio tests on the operating transformers. The traditional variable ratio bridge is cumbersome to operate, the readings are not intuitive, and necessary conversions need to be made. The test results are only one phase ratio data.BZC type transformer automatic ratio group testerOvercoming the shortcomings of traditional variable ratio bridge testing.

2、 Security measures

1. Before using this instrument, be sure to carefully read this operating manual.

2. This instrument can be used both indoors and outdoors, but it should be used away from rain, corrosive gases, and excessive dust.

3. Instruments should avoid severe vibrations.

4. The maintenance, care, and adjustment of instruments should be carried out by professionals.

5. Do not connect the yellow, green, and red wires of the test clamp to the A, B, and C wires of the transformer correctly.

6. Do not connect high and low voltage cables in reverse.

7. When testing single-phase transformers, only use yellow and green wire clamps, do not use them incorrectly, and unused test clamps should be suspended.
