product description
The fully-automatic microcomputer control transformer multi-functional comprehensive performance test bench is used to test the no-load and load characteristics of power transformers and distribution transformers, and can also be used for test equipment with frequency-doubling induction and power-frequency withstand voltage tests on tested transformers. This equipment complies with GB/T4776, GB/T5169, GB/4285-1993 and other relevant national standards. The fully automatic microcomputer control transformer multi-functional comprehensive performance test bench mainly tests the no-load and load characteristics of power transformers and distribution transformers, and can also perform frequency multiplication induction and power frequency withstand voltage test on the tested transformers. The measuring part of the device is controlled by a high-end MCU. The digital display, no-load, short-circuit and other test data are sampled synchronously by the MCU, which avoids the errors in the traditional test method in which the voltage, current meter, and power meter are respectively read and manually calculated.
