GDJB-802 3 Phase Secondary Current Injection Relay Protection Test Device plays a key role in operating electricity power systems reliably and safely. It can automatically judge over-current, over-voltage, overload, short circuit, high temperature, abnormal data and warning prompts for misoperation. In addition to the verification of various relays (such as current, voltage, inverse time, power direction, impedance, differential, low cycle, synchronization, frequency, DC, intermediate, time, etc.) and microcomputer protection, it can also simulate single-phase to Three-phase transient, permanent, and transitional faults are tested for the entire set. It can also complete various large-scale and complex calibration tasks with a high degree of automation, can automatically test and scan various protection settings, store test data in real time, display vector diagrams, and print reports online.
It can independently complete device testing in professional fields such as microcomputer protection, relay protection, excitation, measurement, fault recording, etc. It is widely used in scientific research, production and electrical test sites in electric power, petrochemical, metallurgy, railway, aviation and other industries.
