CT VA Characteristic TesterDarui Electric recommends：
CT VA characteristic comprehensive tester is a multi-functional field instrument designed for testing CT: VA characteristic, ratio, polarity, error curve, knee point calculation, and secondary loop inspection.。Set test voltage/current, device auto boosts and displays VA curve (indirect sampling) or ratio/polarity results. Supports data save and on-site printing, USB upload.Features● Safe and Reliable: Pioneering MBC power control, single-phase AC220V input, shared port for working and power supply.
Note: Other products use separate inputs requiring 3-phase AC380V, posing electric shock risks.
● Compliant with National Maintenance Regulations:
All outputs are real voltage/current values with standard sine wave, 50-60Hz; effectively simulates actual CT status, compliant with national standards.
● Large Output Capacity:
Single unit: max 0-1000V output, max 0-600A current output at 220V input, ideal for field maintenance.
● Comprehensive Functions:
Tests CT VA characteristic, ratio, polarity, 5% and 10% error curves, primary current injection and demagnetization — multi-purpose in one unit.
● Simple Wiring:
Single power input port; only 6 test ports for all CT tests, safe and simple wiring, ideal for field use, reducing labor and improving efficiency.
● Fast Printing:
Thermal printer with auto data selection for typical reports, perfect for field data comparison.
● Large FLASH Storage: Stores 1000 test data sets, retains 10 years after power-off.
● USB Interface: Easy connection to modern laptops.
● Compact & Lightweight: Convenient for field use.
