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.
