DOC-2000™ -
ndb Technologies Inc.
The DOC-2000™ is a test instrument designed for distribution networks transformers up to 167KVA. It can determine the presence of short circuits or an open circuit in the distribution transformer primary winding & also short circuits on the secondary winding. The DOC-2000™ is designed to be operated from an arial device or from the ground at the end of a hot stick without disconnecting the transformer’s secondary windings.

-
Weshine Electric Manufacturing Co., Ltd
After a DC current test, such as winding resistance measurement, the magnetic core of a power or instrument transformer may be magnetized (remnant magnetism). It can cause various problems such as wrong diagnostics, inaccurate measurements on a transformer, inrush current at the start-up of a power transformer, or incorrect operation of protective relays due to magnetized CT cores.

6691 -
Kingrun Instrument Co., Ltd.
applying ±90V voltage on the winding of the transformer demagnetized and get the voltage value on the terminal and the current value in the winding to draw the hysteresis characteristic curve. This method can be used for linear quantitative analysis of residual magnetism in transformers, and fast demagnetization can be achieved by tracking hysteresis curves. The analyzer can measure magnetism residual rate before and after demagnetization.
