The CTMP 2012 is a light weight, portable, instrument transformer test set. This instrument is unique in offering 0.1% ratio accuracy over the entire range of measurements.

The CTMP 2012 is the most powerful CT test set ever built with 64MB RAM, 1GIG FLASH, and a 32BIT, 400MHZ, ARM9 processor. Same awesome accuracy but now with a state of the art 7", 800 x 480, touch screen that offers built in instructions and breathtaking data presentation.

The CTMP will write data directly into a supplied Excel spreadsheet template for efficient, as you test, data sheet creation that includes a saturation graph. The unit links to a PC via supplied serial cable or optional Bluetooth link. The CTMP performs a complete array of tests of an instrument transformer and the secondary circuit. Current transformers can be tested when installed in power transformers, switchgear, and circuit breakers.

Voltage and current inputs are provided to allow the unit to measure an external voltage, current and phase angle. Current may be measured using the 0-10A hardwire input or a supplied fluke clamp on that allows "non invasive" measurement to 100A. The unit therefore eliminates the need for the expensive phase angle and other meters previously required to commission a protective relay or metering scheme. The new display allows a vector graphic presentation of AC quantities. The CTMP also offers the unique ability to ratio an energized CT !
