The CT/PT Analyzer CTP-120PA is the revolutionary testing system for various CTs and PTs according to IEC and IEEE/ANSI standard. The Analyzer can automatically complete the test within seconds by one click of the patented multifunctional rotary mouse. It allows to test the knee-point voltage up to 40kV CTs and PTs on-site in power grids or in manufacturers' production facilities or test labs.

CT/PT Analyzer CTP-120PA is capable of testing multi-ratio CTs automatically without the need for rewiring, up to 6 connections for the secondary side of CTs.

The main features of CT/PT Analyzer CTP-120PA are as follows:

●Able to test Protection CTs, Measuring CTs, TP class CTs and inductive PTs

●Test excitation characteristic and error curve based on low-frequency measurement principle 

●Measure ratio, polarity, ratio error and phase displacement error based on voltage method

●Capable of testing multi-ratio CTs automatically without the need for rewiring

●Adopt patented multifunctional rotary mouse to replace the keypad 

●Adopt 5.7 inches LCD screen for display

●Adopt DSP, ARM and embedded LINUX operation system

●Both local test and PC remote test available

●Higher measurement accuracy: 0.05 %

●Print test results directly by built-in thermal printer

●Small and light weight (9kg / 19.84 lbs) for easy transport
