Grid power for hydrocarbon service applications

A grid power system for distribution of electrical power at a well site, comprising:

• a main breaker coupled to an electrical power source, wherein the main breaker includes a current monitoring system which monitors current at one or more output lines of the main breaker, wherein the main breaker is opened when the current at the one or more output lines equals or exceeds a preset current threshold;
• one or more grid power units coupled to the main breaker;
• and
• one or more loads coupled to the one or more grid power units, wherein the one or more grid power units transform a line voltage received from the main breaker into a plurality of lower voltage levels below the line voltage for output to the one or more loads.

A method for distributing electrical power at a site, comprising:

• coupling a main breaker to an electric power source, wherein the main breaker includes a current monitoring system which monitors current at one or more output lines of the main breaker, and wherein the main breaker is opened when the current at the one or more output lines equals or exceeds a preset current threshold;
• coupling a first switchgear unit to the main breaker;
• coupling one or more loads to the first switchgear unit, wherein the first switchgear unit includes one or more load control devices which protect the one or more loads coupled to the first switchgear unit from damage due to power fluctuations;
• and
• coupling one or more communication lines to at least one of the first switchgear unit and the main breaker.
