Abstract
Training labs for training linemen and other power or utility technicians are disclosed. The training labs can be configured to provide equipotential zone (EPZ) grounding training in overhead and/or underground power scenarios. In some instances, the training labs can be mobile. For example, a mobile training lab can comprise an overhead training side that comprises one more deployable overhead power poles and/or an underground side comprising one or more component cabinets.
Claims19
A training lab for providing EPZ grounding training, the training lab comprising:
- at least one portable power pole assembly configured to support a power line, wherein the at least one portable power pole assembly is extendable and retractable and wherein the at least one portable power pole assembly is electrically isolated from the training lab;
- a portable three-phase power source configured to selectively energize the power line;
- and
- a lineman meter configured for use during EPZ grounding training, the lineman meter comprising:
- an arm lead;
- a leg lead;
- an internal resistor positioned between the arm lead and the leg lead and that represents a resistance of a human body;
- and
- at least one indicator configured to indicate proper or improper grounding determined through detection of a current that represents a fatal shock.
A training lab for providing EPZ grounding training, the training lab comprising:
- at least one cabinet comprising a single-phase or a three-phase transformer, wherein the at least one cabinet is electrically isolated from other cabinets;
- a portable three-phase power source configured to selectively energize the single-phase or the three-phase transformer;
- and
- a lineman meter configured for use during EPZ grounding training, the lineman meter comprising:
- an arm lead;
- a leg lead;
- an internal resistor positioned between the arm lead and the leg lead and that represents a resistance of a human body;
- and
- at least one indicator configured to indicate proper or improper grounding determined through detection of a current that represents a fatal shock.
