The CTX-2000 (older model) Current Transformer Tester Features

- Up to 1200 Volts test voltage
- Up to 1.5 Amperes output
- Automatic display of ratio up to 2000:1
- An important tool for commissioning, troubleshooting and preventive maintenance
- Measurement of any ratio of current transformer
- Indication of CT polarity
- Ultrastable digital instruments test excitation and test saturation current
- Bar-graph meter gives quick indication of current "tip-up"
- All tests are performed without changing excitation test setup
- Internal bushing current transformers can be tested inside transformers or switchgear
- Fully protected against overload or short circuit
- A "RUN/HOLD" switch will "freeze" readings on all digital meters

A SATURATION test is performed by applying voltage to the current transformer which increases the test current linearly until near saturation at which time a large increase of current is easily seen on the bar graph meter and accurately read on the digital ammeter.

RATIO test is the result of voltage comparison between primary and secondary voltages - easily calculated into ratio and displayed by the flip of a switch.

A POLARITY test is performed by measuring a phase sensitive comparison circuit and indicated by two distinct pilot lights.

A zero start interlock and high-speed circuit breakers protect the test instrument and current transformer under test.

All tests can be performed with one setup without changing leads or switching settings. Autoranging meters eliminate range switches.

Current transformers can be tested while mounted in bushings.
