The power factor is determined by the cosine of the phase angle between voltage and current. In AC circuits, the phase angle between voltage and current is aligned, or in other words, zero. But, practically there exists some phase difference between voltage and current. The value of the power factor always lies between 0 and […]

An RCCB (Residual Current Circuit Breaker) is a safety device designed to protect people from electrical hazards. It immediately disconnects the power supply when a residual current (leakage current) exceeding the permitted limit is detected, typically caused by leakage through a person or to the ground. Applicable Standards for RCCB IEC 61008-1 specifies the general […]
