Complete CT Testing with Vanguard’s EZCT Series of Testers

  • Uncategorized

Environmental and mechanical factors can lead to the degradation of a current transformer triggering arcing and eventual failure. Current transformer or CT testing provides information about the condition of the current transformer.

The EZCT series of testers from Vanguard allow you to conduct automatic CT, current ratio and winding polarity tests.These testers apply a variable AC test voltage to the current transformer’s secondary windings. The EZCT then records the test voltage and excitation voltage injected to the CT during the test. The EZCT testers also have a built-in thermal printer that lets you plot up to 10 knee-point voltages and excitation curves. The testers can also calculate and print out IEEE-30, IEEE-45, ANSI/IEC 60044-1 knee-point voltages.
