Electrical Switchboards – Overcurrent protection – overload, short circuit, discrimination and cascading Overcurrent Protection Overcurrent protection comes under two main categories, Overload protection and short circuit protection. Overload protection Overload protection aims to protect conductors from the thermal effects of passing more current than...
Cascading and selectivity are two important concepts in designing power system protection and back-up. The principles of cascading and selectivity ensure systems’ reliability, protection, and cost-effectiveness while operating under a variety of fault conditions. Selectivity (Discrimination) Selectivity, or discrimination, is essential to ensure the...
