CT & VT Analyzer with Multi-tap Switch Box
Model: CTP-120PA
The CT & VT Analyzer CTP-120PA is a lightweight and portable unit capable of testing both current transformers and voltage transformers.
At less than 9kg(19.84 lbs) the CTP-120PA is a highly portable unit that also offers accuracy in testing. Capable of performing saturation, ratio, polarity and winding resistance on current transformers, the CTP-120PA can also be used for testing metering and protection class voltage/potential transformers.
The CT & VT Analyzer CTP-120PA provides a microprocessor controlled variable voltage and current output along with precision instrumentation for automatically testing single and multi-ratio CTs and VTs. The equipped multi-tap switch box makes testing multi-tap CTs easy. It will directly connect to multi-ratio CT and perform ratio tests on all taps with the push of a button and without changing leads. This will greatly reduce testing time.
The CT & VT Analyzer CTP-120PA can be controlled via its high resolution and sunlight 5.7-inch TFT LCD screen display. This interface allows the user to perform testing quickly and easily using the patented multifunctional rotary mouse.
The CT & VT Analyzer CTP-120PA can also be controlled via a laptop running CTP testing software based on Windows operating system.
