Selecting 80% or 100%-Rated Molded Case Circuit Breakers According to Philippine Electrical Code
Introduction
Molded Case Circuit Breakers (MCCBs) are used as protection devices to ensure safe operation of electrical circuits against overload, short circuit, and ground faults. MCCBs are used in residential applications, commercial and industrial installations; these breakers are used as a feeder breaker or branch circuit breaker.

Modernization of Electrical Substation Automation Systems Using IEC61850
The most important international standard for substation automation systems is IEC 61850 and its related standards.
The installation of IEDs in substations, when combined with IEC61850, enables interoperability, flexibility, and increased efficiency and creates a wide range of potential solutions for substation operation, protection, monitoring, control, and automation. Modern substation automation (SA) makes use of data from IEDs to...

IEC 61850 Changed Electrical Protection, Control and Monitoring
Intelligent Electronic Devices
Electrical protection is as fundamental to the generation, transmission and distribution of electricity as generators, transformers and transmission lines. A couple of decades ago microprocessor based relays replaced the traditional electromechanical types and from then on, there is an increasing usage in the various types of protection relays and other Intelligent Electronic Devices (IEDs). This was due...Electromagnetic Compatibility (EMC) and its Importance in Power Quality
Electromagnetic Compatibility (EMC) refers to the ability of electronic and electrical systems, devices, and equipment to operate in their intended electromagnetic environment without causing or experiencing interference. This interference can be either electromagnetic interference (EMI), where a device emits unwanted electromagnetic energy, or susceptibility to electromagnetic interference (EMC), where a device is affected by external electromagnetic disturbances.
