Rent a Vanguard EZCT-2000C Plus for Reliable Current Transfomer Testing

Posted by Protec Tech Team on


Vanguard EZCT-2000C Plus Automated CT Test Set .jpgA Current transformer reduces high voltage currents to a lower value and allows for the safe monitoring of electrical current flow.

The principal of operation of a current transformer is somewhat different from that of an ordinary voltage transformer.

Unlike a voltage or power transformer, the current transformer consists of only one or very few turns as its primary winding.

This primary winding can be of either a single flat turn, a coil of heavy duty wire wrapped around the core or just a conductor or bus bar placed through a central hole.

The Vanguard EZCT-2000C Plus Automated CT Test Set a microprocessor-based current transformer test set designed specifically for Current Transformer (CT) testing, offers features that can greatly increase productivity and save time during the commissioning stage.

The EZCT-2000C Plus’s test leads can be connected to all the CT output terminals, and the complete CT test can be performed automatically without any operator intervention.

Excitation Test
CT excitation testing is performed using the ANSI/IEEE C57.13.1 test method, with test voltage ranges from 50, 300, 500,1200 and 2000 Vac can be selected for the excitation test.

CT Winding Insulation Resistance Test
The EZCT-2000C Plus offers an IR test feature that can also measure the insulation resistance of the CT’s secondary winding using a test voltage up to 1000 Vdc.

Ratio and Polarity Tests
CT current-ratios are determined using the ANSI/IEEE C57.12.90 measurement method.

Demagnetization
The test set automatically demagnetizes the CT under test when performing an excitation test.

Winding Resistance Test
The test set can measure the DC resistance of transformer windings from 100 micro-ohms to 10 ohms.

CT Burden Test
The EZCT-2000C Plus can measure the CT’s actual connected burden by injecting a 1A or 5A test current into the load.
