The basic reasons for grounding or not grounding the electrical system and the various types of system grounding, as well as the practices commonly used to ground electrical systems are discussed. Purpose: Grounding of an electrical system is a decision that must be faced by engineers charged with planning or modifying electrical distribution.
Grounding of an electrical system is a decision that must be faced by engineers charged with planning or modifying electrical distribution. Grounding in some form is generally recommended, although there are certain exceptions. Several methods and criteria exist for system grounding; each has its own purpose.
A best practice is to implement a maintenance routine that includes electrical ground resistance measurements to monitor the state of the grounding system. low impedance path back to the source in order to clear fault currents, minimize ground potential rises, and most importantly maximize safety.
Methods of system neutral grounding Most electrical systems employ some method of grounding the system neutral at one or more points. Similar to the IEC T and I designations, these methods can be divided into two general categories: solid grounding and impedance grounding.
