Arc flash assessment based on IEEE 1584 has limitations with respect to the voltage. The voltage range applicable to IEEE 1584-2018 remains unchanged at 208V through 15kV. Low voltage range …
Protection coordination is the heart of all power systems. To ensure a quality and reliable operation of the power systems, an electrical fault must be cleared within a short time. …
Typical Protection Relay Timing Errors Protection relay grading intervals are critical in ensuring selective coordination in power systems. The recommended protection relay grading intervals typically depend on the type of …
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 …
Hazardous Area Classification Oil & gas installation has areas which are classified as being Zone 1 or Zone 2 according to IEC 60079. With regards to explosion ignition of flammable …
