Design of Grounding / Earthing System in a Substation Grid

Introduction to Substation Earthing Grid. In high and medium voltage Air Insulated Substations (AIS) the electromagnetic field, which causes are the static charges of bare cable and conductors and by the atmospheric conditions (surges), induce voltages at no-live parts of the installation that create potential differences between metallic parts and …

Disconnect Switches in Substation: Types, Design and Working

A disadvantage of grounding blades is that they provide a safety ground in an unchanging location, whereas portable safety grounds can be placed at any location to achieve a ground point for personnel safety. Fixed position grounding blades are commonly used with capacitor banks to drain trapped charges from the banks.

PCB Marked Capacitor on the left Capacitors By 1976, 95 % of the capacitors produced in the United States were filled with PCBs13 (Fig.3). PCB capacitors contain the pure aroclors, 1242 or 1016. Manufacture before July 2, 1979, or a PCB trade name on the nameplate is a good indicator of high concentration PCBs.

Checking Power Capacitor Banks for Failed Capacitors

Shorted Capacitors - Typically the DMM will show over-load or -O.L- for a completely shorted capacitor. Open Capacitors - Typically the DMM will show a "di.sc" or a very low capacitance reading (capacitance reading in the 0 to 1 nF). Partially Failed Capacitors - Typically the DMM will show a capacitance reading that is more than 10% greater than …
