HMJBC-802 Three Phase Relay Protection Test Kit

Microcomputer Relay Protection Tester,
Relay Protection Tester,
Three-phase Relay Protection Calibrator

Product Description


The three-phase relay protection tester is a new type of miniaturized microcomputer relay protection tester that fully utilizes modern advanced microelectronic technology and devices. It adopts an advanced structure that operates independently on a single machine and can also be connected to a laptop for operation. Equipped with a large screen LCD display and a flexible and convenient rotating mouse controller. Single machine independent operation already has strong functions and can perform most experiments, while connecting to a computer for operation has more powerful operating functions. Small size and high accuracy.
