Modular Residual Current Device : It is a device that automatically cuts off the DC converter of a solar cell generator when ground accident noticed. It contains sensor, signal processing unit and breaker to avoid the ground fault automatically and continuously.
Why we need Residual Current Device Type B? : Where a photovoltaic power generator has a ground fault or a large Stary Current by parasitic capacitance, GPT loss, double grounding fault, inverter IGBT loss, power loss, electric shock corrosion and others will be affected. Residual Current Device (RCD) Type B is mandatory device to prevent such accidents.
