Harmonics Limit – What is the difference between the IEC and IEEE?
The IEC (International Electrotechnical Commission) and IEEE (Institute of Electrical and Electronics Engineers) both have standards that address harmonics in electrical systems, but they differ in scope, methodology, and application. …
Circuit breakers with motor protective characteristics
Circuit breakers with motor protective characteristics, often referred to as Motor Protection Circuit Breakers (MPCBs), are specialized devices designed to protect electric motors from electrical faults and overloads. They combine …
Derating of the Rated Service Short-Circuit Breaking Capacity (Ics)
Definiton Rated Service Short-Circuit Breaking Capacity (Ics) represents the maximum fault current the circuit breaker can reliably interrupt multiple times without requiring maintenance. Derating of the Rated Service Short-Circuit Breaking …
A comparison between XLPE and EPR as insulating materials for HV cables
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 …
