sharp price secondary injection relay test set instrument  for protection relay

Brief introduction
Secondary current injection test set not only used for test all traditional relays and protection devices, but can also carry on all kinds for modern various microcomputer protection, especially for transformer differential protection and automatic transfer switch equipment.

Main Features

1. Six phase voltage and six phase current can be output, which has made it is possible to be any combination.
2. Available to connect with a computer or a desktop compute directly .
3. Output port with high fidelity and high reliability function and excellent performance.
4. The output part adopts DSP control, which has fast operation, real-time digital signal processing capability, wide bandwidth and high resolution D/A conversion control.
5. It can complete all kinds of high automatic validation work which is large and complex.
6. 110V and 220V adjustable DC power is designed to supply output.
7. With USB communication port can communicate with the computer and other external devices.
8. With power soft start function and the software of the fault self-diagnosis and the output latch function.
