Types and Applications Of Overcurrent Relay
Distribution systems are susceptible to overcurrent flow within its components. Overcurrent may arise from abnormal system conditions, including overloads and short-circuit failures, or from typical system conditions, such as transformer inrush current and motor initiation. Consequently, under typical system conditions,… Read more

How to locate underground faults on cable?
A common approach to test cable and determine insulation integrity is to use a Hi-pot test. In a hi-pot test, a DC voltage is applied for 5 to 15 min. IEEE-400 specifies that the hi-pot voltage for a 15-kV class… Read more
