As you already know, reliable overcurrent protective devices, such as fuses and circuit breakers, prevent or minimize costly damage to transformers, conductors, motors, equipment, and the other many components and… Read more
The principal object of transformer maintenance is to maintain the insulation in good condition. Moisture, dust and excessive heat are the main reasons of insulation deterioration and avoidance of these… Read more
The protection of shunt capacitor banks against internal faults involves several protective devices in a coordinated scheme. Typically, the protective elements found in a shunt capacitor banks (SCB) for internal… Read more
The National Electrical Code (NEC) covers grounding and bonding in several articles, but the primary coverage is in Article 250. Typical commercial electrical systems are grounded systems. Within the system,… Read more
Ferroresonance is a non-linear resonance phenomenon that can affect power networks. The abnormal rates of harmonics and transient or steady state overvoltages and overcurrents that it causes are often dangerous… Read more
A few practical methods of reducing noise will be examined in this technical article. These include a quantitative consideration of the effects of shielding, cable spacing, earthing (or grounding) and…...
