Description
Overview
The Vanguard Instruments EZCT-1200 is a microprocessor-based, portable current transformer (CT) test set designed for field testing of current transformers in their mounted configuration. This rugged instrument eliminates the need to remove bushings or transformers from the host equipment, reducing downtime and improving field efficiency. The EZCT-1200 performs three critical CT tests: excitation, current-ratio, and winding polarity.
Key Features
- Excitation testing per ANSI/IEEE C57.13.1 and IEC 60044-1
- CT current-ratio testing per ANSI/IEEE C57.12.90
- Winding polarity determination (in-phase or out-of-phase)
- Variable test voltage output up to 1,200 Vac
- Current measurement range: 0-10A
- CT ratio measurement range: 0.8 to 5,000
- Phase angle measurement: 0-360 degrees
- Built-in 4.5-inch thermal printer for test reports
- Back-lit LCD display (20 x 4 lines), readable in bright sunlight and low-light conditions
- Knee-point voltage calculations and plotting (IEEE-30, IEEE-45, ANSI/IEC 60044-1)
- Memory storage: 128 test records with up to 10 data sets per record
- RS-232C and USB connectivity for data transfer and software control
- Included Windows XP/Vista software for test management
Applications
- Utility and industrial power system CT testing and maintenance
- Field diagnostic testing in electrical substations
- Condition assessment of current transformers in service
- Compliance testing for electrical equipment
