| Relay Protection Star |
Working Principle:
The relay protection test box/relay protection tester instrument is divided into two circuits: the main circuit and the auxiliary circuit. The main circuit is adjusted by a large knob, and the auxiliary circuit is adjusted by a small knob. The main circuit controls the various output quantities through the "Output Selection" button switch on the panel, and each time the output is switched, the digital voltage/current meter on the instrument can automatically monitor its output value. The auxiliary circuit directly adjusts the output through the output switch control, and the measurement can be done with an external multimeter.
