A network of 4 0 awg bare copper conductors buried 12 to 18 inches below grade in a grid pattern spaced 10 to 20 feet apart and extending outside the perimeter fence.

Grounding system of substation. First it provides a means of dissipating electric current into the earth without exceeding the operating limits of the equipment. The grounding system is design to protect sensitive equipment the environment and people who come in contact with the substation. When a fault occurs due to short circuit currents caused by ground faults lightning or transmission line faults the grounding system should be able to safely ground the surging current into the ground. Ensure safety to personnel in substations against electrical shocks.

The functions of grounding systems or earth mat in include. Introduction to power system and substation grounding course overview. The grounding system in substation is very important. The total ground potential rise and the gradients in potential during a fault called touch and step potentials must be calculated to protect passers by during a short circuit in the transmission system.

A typical substation grounding system designed for installation in low resistance soil per standard 80 might look something like the following. 5 will reduce both grid resistance and grid voltage rise. Safe operation of a substation calls for a properly designed and installed grounding system. Increase your awareness of substation and power system grounding principles and practices.

The proper grounding of a substation is essential and very important for the following two reasons. Discharge the overvoltages from overhead ground wires. This course is focused on grounding applications for electric utility and complex commercial and. The substation grounding system contains of a grid earth mat formed by a horizontal buried conductors.

A well designed grounding system will ensure reliable performance of the substation over its entire service life. Provide the ground connection for connecting the neutrals of stat connected transformer winding to earth neutral. An electrical substation is a critical resource in a power system. The substation grounding system is an essential part of the every electrical system.

Tying the fence ground into the main ground grid as shown in fig. Some substation designs require fence grounding to be isolated from the main ground grid. The grounding system in substation is very important.
