160V Ratio Test Instrument - Four-Level Undertaking Equipment Qualification Functions
Fully automatic transformer ratio and group test instrument The main function and purpose is to test the turns ratio or voltage ratio of transformers periodically according to the preventive test regulations of the Ministry of Electric Power, during the production process of semi-finished and finished power transformers, before new transformers are put into operation, and during the operation of transformers in the power system. The traditional ratio bridge is cumbersome to operate, the readings are not intuitive, and necessary conversions are required, with the test result only providing data for one phase ratio. The fully automatic transformer ratio and group test instrument overcomes the shortcomings of traditional ratio bridge testing. The screen completes the three-phase ratio test at once, with fast test speed and high accuracy. It greatly saves on-site testing time and brings high efficiency to customer tests.
Precautions:
1. Be sure to read this operation manual carefully before using this instrument.
2. The operator of the instrument should have general knowledge of electrical equipment or instruments.
3. This instrument can be used indoors and outdoors, but should avoid use in rain, corrosive gases, excessive dust, high temperature, and direct sunlight.
4. The instrument should avoid severe vibration.
5. Maintenance, care, and adjustment of the instrument should be carried out by professionals.
6. The yellow, green, and red test clips correspond to phases A, B, and C of the transformer, do not connect incorrectly.
7. Do not reverse the high and low voltage cables.
8. When testing a single-phase transformer, only use the yellow and green clips, do not use the wrong ones, and unused test clips should be left suspended.
