WebDesign Criteria There are two main design goals to be achieved by any substation ground system under normal as well as fault conditions. These are: 1. To provide means to dissipate electric currents into the earth without exceeding any operating and equipment limits 2. WebIEEE Std 80-2000: IEEE Guide for Safety in AC Substation Grounding. ... As a general rule, if an earthing grid design satisfies the requirements for safe touch potentials, it is very unlikely that the maximum permitted step potential will be exceeded. The IEEE 80 standard uses the maximum mesh voltage as the touch voltage, and this usually ...
The matter of grounding systems in substations is vital. The main functions of a grounding system are: 1. Provide the neutrals of generators, transformers, capacitors, and reactors a connection to the earth 2. Offer a low impedance path to the earth for the currents coming from ground faults, lightning … See more Substation safety requires the grounding and bonding of all exposed metal parts.
