This advanced instrument performs all tests needed to commission an instrument transformer. Current transformers can be tested when installed in power transformers and other apparatus. In addition to very precise and automated ratio, polarity and saturation testing the CTMP includes a power system meter with phase angle that allows in service verification of the CT and secondary circuit. Capability also includes performance of an energized ratio and polarity test, secondary injection test, and burden test.

The CTMP will save data to a flash drive for writing into Excel or other program for efficient data sheet creation. You can leave the lap top behind and just take your test set out to the equipment. You can even leave the instruction book behind as the CTMP offers integrated instructions.

RATIO TEST: The instrument performs the classic voltage ratio test with 0.1% accuracy and displays the primary and secondary voltages, the angle between them (polarity), and the calculated ratio. Two X1 - X2 excitation output voltage ranges, 0-200V and 0-1000V, facilitate accurate measurement of CT ratios to 100,000 to 5. A potential transformer test mode tests potential transformers to 3000 to 1. Data may be automatically saved to a flash drive.

SATURATION TEST: The CTMP excitation test mode offers two voltage ranges, 0 - 200VAC and 0 - 1000VAC. In saturation test mode the unit displays exciting current and voltage. A real time graph is plotted on the screen during performance of the test allowing observance of the knee. A distortion measurement identifies the spike in the exciting current waveform as the core saturates and flags this point by displaying the current value in red. Data may be saved to flash drive.

AC POWER SYSTEM METER: Now even better then ever with vector graphics and integrated instructions. The E and I inputs may be used to measure a voltage, a current and the phase angle (I lag E). The meter also calculates and displays Watts, VARS, Voltamps and Power Factor. The CTMP offers metering functions designed to perform "in service" or "load" testing of power system meter and relay circuits. The clamp on permits the measurement of two currents and is convenient for commissioning tests of differential relays. The unit also allows measurement of ratio and polarity of energized CT's installed in low voltage equipment.

SECONDARY INJECTION AND BURDEN TESTS: The Secondary Injection mode meters the current output at the X1-X2 terminals and the current input at the hardwire I terminals or the clamp on. The unit also measures the angle between these currents. The hardwire or clamp input is selected from a convenient menu. The burden test measures the impedance presented at the secondary terminals of the CT.
