■ Functional features
▲ Can be one-time high, low voltage current, voltage test line all connected to the transformer, the test process does not need to be inverted test line.
▲ For the winding test with neutral star connection method, can take the way of testing three-phase resistance value at the same time, greatly saving the test time.
▲ For three-phase five-column low-voltage internal Angle transformer of low-voltage side direct resistance test, can use automatic magnetic method, fast test speed.
▲ Can display and print all the test data of the high, medium and low voltage winding of the transformer, and automatically calculate the three-phase unbalance degree, and can also print the resistance data converted to the rated temperature.
▲ With perfect back potential protection function.
▲ The instrument can permanently store the test data, but also can use the U disk to store data.
▲ The instrument has the characteristics of wide temperature adaptation, high precision, shockproof, anti-interference and easy to carry.
▲ The instrument has the function of eliminating residual magnetism, automatically degaussing AB and BC. Vs-3310b can eliminate the residual magnetism once.
