1 ASJ series digital measuring relay
1.1 Overview
ASJ series digital measuring relay (hereinafter referred to as relay) adopts 32-bit high-performance CPU, real-time sampling three-phase alternating current, three-phase AC voltage signal, and adopts RMS calculation method to achieve higher precision in a wider frequency range. Measurement. Integrated with a variety of protection functions, you can achieve protection input or exit, alarm or trip with simple selection; high precision, low power consumption, fast action, high return coefficient, no jitter, can be used for voltage monitoring (voltage type: Such as generators, transformers and transmission line relay protection, etc. or current monitoring (current type: such as overload of motor, transformer and transmission line and short circuit protection circuit), as overvoltage, undervoltage, overcurrent, Blocking action element or starting element for undercurrent, overfrequency, underfrequency protection.

2 ASJ Series Intelligent Residual Current Relay
2.1 Overview
ASJ series residual current action relay can be combined with low voltage circuit breaker or low voltage contactor to form a combined residual current action protector. It is mainly used for TT and TN system distribution lines with AC 50Hz and rated voltage of 400V and below. The electrical circuit is protected against ground faults to prevent equipment and electrical fire accidents caused by ground fault currents, and can also be used to provide indirect contact protection against personal electric shock hazards. The product meets the requirements of the national standard "GB/T 22387-2008".
