I,Overview
This relay protection test box is another new type of relay protection test equipment developed by our company. With the main body unchanged, it weighs only 15 kilograms, adopts stainless steel or plastic-aluminum casing, which is beautiful, sturdy, and has good shock absorption performance. It uses a dual carbon brush voltage regulator (i.e., double-sided voltage regulator), with a large knob to adjust heavy-load AC/DC voltage and current, and a small knob to adjust light-load AC/DC voltage and current, allowing two outputs simultaneously. It adopts a 0.5-class digital meter and high-precision sensors for accurate measurement, and uses a six-digit digital electric stopwatch to meet time measurement requirements. It is indeed a good tool for relay protection personnel working in the field.
