What is GFCI or GFI? A ground fault circuit interrupter, called a GFCI or GFI, is an inexpensive electrical switchgear device that can either be installed in your electrical system or built into a power cord to protect you from severe electrical shocks. Electric shocks can cause severe injury or even death. Even exposure to current as low as 100 ma current for only … [Read more...] about GFCI (Ground Fault Circuit Interrupter) – Working, Types, Installing and Troubleshooting
The auto reclosing of power lines has become a generally accepted practice. Reports from different parts of the world show that in certain networks in regions subject to a high lightning intensity only about 5 percent of the faults are permanent. Auto-reclosing, therefore, provides significant advantages. Outage times will be short compared with systems where station … [Read more...] about Auto Reclosing of Power Lines and Types of Faults
