30mA RCD Sensor 6mA DC Earth Leakage Detection RCM for Solar
MD0630T41A is a AC DC integrated leakage current sensor with high sensitivity, accurate measurement, small size, UART communication, Modbus protocol, etc.
Leak detection is a key test for systems and components within the battery pack from cells, contactors, cooling system and the enclosure. Leaks in lithium-ion battery cells can shorten battery life and deplete energy capacity. Leaks also can allow moisture to enter the battery system.
The versatility of leakage current detection extends across critical applications in EVs and PV systems: For EV Charging Stations: Advanced RCDs ensure prompt detection of leakage currents, mitigating the risks of electrical shocks and system failures.
Traditional leakage current detection systems often rely on complex architectures with multiple discrete components, microcontrollers, and external power management. A streamlined approach is essential for keeping costs, size, and design effort under control.
It is easy to tell from the formula for leakage current (shown above) that the larger the PV panel area (S), the higher the conductivity (ε) of air, and the shorter the distance (d) between the PV panel and ground or roof, the higher the leakage current will be.
