Fully Automatic CT/VT Test System

Model: CTP-120PA

CT/VT Test System CTP-120PA is a fully automatic Current and Voltage Transformer test system, especially designed for testing CTs, VTs and Combined Transformers.

CTP-120PA grants a faster testing, due to its Multi-tap Switch Box which allows to connect directly up to 6 taps, in this way the connection of the device is made only one time and without the need of any further manual operation.

The main tests performed by CTP-120PA are: Excitation, Accuracy, Ratio & Phase Error, Resistance and Burden and they are all executed in fully automatic mode, without user intervention. All tests are performed by generating current and voltage.

All the functionalities are managed by a sunlight 5.7-inch readable TFT LCD screen display, patented multifunctional rotary mouse, ARM and embedded LINUX operation system, designed for the outdoor environment and without a laptop.

Test results are kept in a local memory, and can be transferred to a PC via USB flash disk.
