Vanguard EZCT Series of CT Testers Offer Heavy Duty Preformance

  • Uncategorized

The Vanguard EZCT series of current transformer testers can perform excitation tests as specified by the ANSI/IEEE C57.13.1, IEC 60044-1 methodology. 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.
