Different types of protection for electrical systems and networks. Different electric protection methods, system & devices, power system, overhead lines & bus bar. What is System. Protection? System protection is the art and science of detecting problems with power system components and isolating these components.
Purpose of Protection System. • Minimize damage. • Leave unaffected equipment in-service. • Maintain equipment operating limits. • Maintain electrical system. Electrical Protections Theory. Electrical protection – device checking power system part operation (G,. T, V) = protected object, to ensure normal operation. Is achieved by two main methods. – Time-grading/Current Grading. • Relays are set to operate depending on the time and current characteristics. – Unit systems.
This portion of our website covers almost everything related to protection system in power system including standard lead and device numbers. ELECTRIC POWER, SYSTEM PROTECTION, CONTROL, AND MONITORING OFProtection is the branch of electric power engineering concerned with the. Overlapping zones of protection are provided so that no part of power system remains system can detect and isolate all faulted portions of the electric system .
