At its core, a standard RCD (Type AC or Type A) operates on a simple, elegant principle: it uses a differential current transformer to measure the balance of current between the line and neutral conductors. In a healthy circuit, these currents are equal and opposite, summing to zero. A fault to earth causes an imbalance, which induces a current in the transformer’s sense coil and trips the device.<\/p>\n\n\n\n
However, Type AC RCDs are designed only for sinusoidal AC currents, while Type A RCDs add protection for pulsating DC currents. Neither is designed to detect smooth DC residual currents. This is a critical vulnerability. Power conversion electronics, common in modern systems, can produce smooth DC leakage that saturates the magnetic core of a Type A RCD. This phenomenon, known as “blinding,” effectively turns the safety device into a useless piece of plastic, unaware of any subsequent AC or pulsating DC faults.<\/p>\n\n\n\n
