1. Basic Requirements As a general principle, any generator can be paralleled with any other, provided the voltage and frequency match at the point of interconnection. However, there are practical …
This guide provides a summary of information on protecting various types of electrical equipment, with a primary focus on the application of protective relays for power transformer protection. It emphasizes …
Selecting an appropriate bus protection scheme requires careful consideration of several factors, including bus layout, permissible switching scenarios, availability of suitable current transformers (CTs), and maintenance requirements. High-impedance bus relaying …
Let us compare crosslinked polyethylene (XLPE) and ethylene propylene rubber (EPR) as insulating materials for high voltage (HV) cables. Both XLPE and EPR have their merits, and the choice depends …
Multi-core cables are particularly used for control, instrumentation, computers and telecommunications. These cables carry very small currents in their conductors compared to power cables. These currents feed into very sensitive …
Introduction In power system, grounding or earthing means connecting frame of electrical equipment (non-current carrying part) or some electrical part of the system (e.g. neutral point in a star-connected system, …
