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.

SCR ELEKTRONIKS
The test bench is specially built for low voltage- B, C & D curve MCBs. Specially designed custom built jigs are able to accommodate single, double, three and four pole MCBs. Decades of experience has helped us to design current source (transformer) in a special way such that good current regulation and high accuracy is ensured with a variable range without the use of any variable transformer in the system. The product is better than the competition with conventional technology at a lesser price!

Arc Furnace Reactors are serially connected reactors that are installed in the supply systems of arc furnace transformers to stabilize arc and limit the unstable arc furnace current and voltage drop which optimize their melting process. These buffer reactors are connected in series to the primary side of the furnace transformer. Typically these reactors are tapped coils and manufactured as per customer'stap requirements.

Osborne Transformer Corp.
Osborne Potential Transformers (PT’s) are used to reduce higher system voltages to lower values that are appropriate for instrumentation and/or protection circuits. They have been designed to meet specified current ratios, and burden impedance at a specified transformation error. One area of unique Osborne expertise is in designing for phase shift when potential transformers are to be used for power measuring applications.

Datexel
The DAT5023 I is an AC or DC current converter, the input current range is selectable on order from 0-5Amps, 0-10Amps, 0-20Amps, 0-25Amps, 0-30Amps, 0-40Amps, 0-50Amps, 0-60Amps. It measure the current with the use of a Hall effect transducer. There is a coil (current transformer) inside the current converter which is isolated from the current input. The cable passes through the housing of the converter and the coil and the true root mean square measurement is taken from this coil then converted to a standard industrial signal output.
