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.

Software Packages
GLUON
The software uses notched specimens (CT specimens) to evaluate the material elasto-plastic fracture toughness value (JIC). The test is conducted at constant loading rate under test-force control or CTOD control and the load is removed to calculate the crack length. The software plots graphs of the crack length increase (Δa) and crack growth resistance (J value) from the acquired data, calculates the JIC value, and evaluates its validity.

CT Admittance Tester
505B
Red Phase Instruments Australia Pty Ltd.
Field testing kWh meters is easy, field testing CTs when live is much more difficult. Our admittance tester can test CTs live with 50Hz or 60Hz current in the metering circuit. This technique does not confirm the accuracy of a CT but it will detect faults that give metering errors, such as shorted turns, metering circuits shorted to ground and tampering of CTs. CT faults can cause large revenue losses. Admittance testing only adds 10 minutes to a routine polyphase meter test, giving cheap insurance.
