Transformer Demagnetization Tester
-
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.

NI-9208, 500 S/s, ±20 mA, 16-Channel C Series Current Input Module
780968-01
Current Input Module
500 S/s, ±20 mA, 16-Channel C Series Current Input Module - The NI‑9208 is designed with industrial systems in mind. It includes a high-resolution mode with 50/60 Hz rejection to remove low frequency noise. It has high-channel density to reduce the number of modules needed, which leaves slots open for other measurement types or for reducing the overall per channel cost of the system. The NI‑9208 uses a standard D‑SUB connection for use with cables and connector blocks.

High Current Test System
-
HIGHVOLT Prüftechnik Dresden GmbH
High current test systems are used to test the thermal stability of equipment and components. The test system induces a current in the test object causing it to heat up. Therefore, the test object is designed as a shorted circuit. The high current test system measures the temperature of the test object at various points, in addition to the current. As a special feature, the temperature that the test object should reach can be specified and the amount of the current can be automatically calculated by the HIGHVOLT test system.

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.

If ultra-low noise performance is required, our integrated two stage devices are the number one choice. With input inductances from 24 nH to 1.8 µH and a flux-noise level as low as 0.8 µPhi0/sqrt(Hz) an energy resolution of about 45 h is attained. The devices consist of a 16 SQUID series array as amplifier stage and a single front-end SQUID.
