Transformer Resistance Testing
-
Transformer insulation resistance deterioration is one of the most common causes of transformer failure: a failing transformer is a costly replacement in an electrical system with the potential for a long downtime. If you fail to maintain your transformer with regular insulation resistance testing (as can be carried out by the Megger Transformer Ohmmeter (MTO) series of transformer test equipment) then it’s likely to fail before reaching its maximum operating life.

4 Channels, MIL-STD-1553, Dual Redundant, Transformer Coupled, Assisted Mode Capable (AMC)
FTC
-
MIL-STD-1553 is a military standard published by the United States Department of Defense that defines the mechanical, electrical, and functional characteristics of a serial data bus. It was originally designed for use with military avionics, but has also become commonly used in spacecraft On-Board-Data-Handling (OBDH) subsystems, both military and civil. It features a dual, redundant, balanced-line, physical layer; a (differential) network interface; time division multiplexing; half-duplex command/response protocol; and up to 31 remote terminals (devices).

Transformer Performance Tester
6691
-
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.

Osborne high impedance transformers are used to step-up, step-down and isolate voltages in single phase and three phase circuits. A properly designed high impedance transformer can be used an an equivalent to an isolation transformer connected in series with an inductor. The high impedance characteristic may be employed as a current limiting feature in both the primary and secondary circuity.
