The Social Benefits of Residual Current Protection Relays

Residual Current Protection Relay to Prevent Accidents

With the continuous development of China's low-voltage electrical systems and economic construction scale, the increase of power electronics equipment, especially the widespread application of rectifiers, inverters, and switching power supply equipment, waveform distortion in lines is becoming increasingly severe. People have higher requirements for improving power supply capabilities and safety, especially in some power supply systems provided by specially independent transformers, where there is weak supervision and the safety of maintenance personnel is not guaranteed. There are often incidents of line equipment touching, leakage, and grounding short circuits causing fire hazards and economic losses. The Residual Current Protection Relay is a better protective device to prevent the above accidents. Its main functions are to protect people from electric shock injuries or fatalities and prevent fires caused by excessive leakage in electrical equipment or lines.

Social Benefits of Residual Current Protection Relay

Residual Current Protection Relay is designed for real-time monitoring of insulation in low-voltage distribution system lines and equipment powered by independent transformers. It provides early warning and leakage protection against leakage accidents and under certain conditions, it offers backup protection against electric shock. This reduces the economic losses and power outage impacts caused by frequent tripping due to sudden changes in leakage points.

Residual Current Protection Relay features continuous real-time monitoring and surveillance of insulation and leakage conditions in system lines and equipment. It leverages high-tech methods to improve safety management, enables remote monitoring, and provides both leakage protection and non-tripping alerts for early detection, warning, and investigation to rationally reduce safety accidents.

Acrel ASJ Series Residual Current Protection Relay products are highly targeted, offering a new method of leakage protection. They play an important role in protecting national assets, ensuring the safety of people's lives and property, and building a harmonious society.

Currently, non-compliance with standards and the improper use of electrical lines and equipment still occur frequently in both under-construction and existing buildings in China. Uncivilized and non-compliant electrical installation practices continually lead to electric accidents and fire hazards. Moreover, in many older large and medium-sized public buildings, including ancient structures, aging cables and improper construction have resulted in decreased insulation performance and the original designed load capacity has become insufficient as electricity usage increases year by year. Residual Current Protection Relay is a reasonable protective device.

As the safety issues of industrial and civil low-voltage electrical systems receive increasing attention and importance, the load is also becoming more critical. Acrel ASJ Series Residual Current Protection Relay products are capable of monitoring the leakage current in lines, and when the leakage current reaches or exceeds the set value, the internal relay operates to issue an alarm and can link with circuit breakers to quickly disconnect the line, ensuring line safety. They play an active role in preventing or reducing various electrical shock accidents caused by electrical insulation issues.
