產品總覽

The EZCT-2000C is Vanguard’s third-generation microprocessor-based current transformer test set. Designed specifically for CT testing, the EZCT-2000C has the following outstanding features that can greatly increase productivity and save time during the commissioning stage.

The EZCT-2000C’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.

Key Features

Performs CT excitation, current-ratio, polarity, and phase angle tests

Measures insulation resistance and winding resistance of the CT seconday windings

Measures the CT’s secondary burden

Test record header information including company, substation name, circuit ID, manufacturer, CT serial number, operator name, and test record-comments

Built-in 4.5-inch wide thermal printer

Plot Multiple Saturation Curves

Stores up to 128 CT test plans and 140 test records internally

USB, Bluetooth, and USB Flash drive interface
