P-5000 -
The Eastern Specialty Company
The P-5000 transformer is a laboratory standard. The unit’s excellent accuracy and the Knopp One-to-One calibrating feature make this precision transformer well-suited as a standard for calibration work. This transformer can provide a very accurate determination of the ratio and phase angle characteristics of current instrument transformers having ratios from 5 to 5,000 amperes. This transformer also can accurately extend the range of a 5 ampere ammeter or wattmeter to cover all current values up to 5,000 amperes.

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.
