Our Products and Services
LEC works as a niche business in the Reciprocating Internal Combustion Engine (RICE) power generation world, supplying a critical component of a larger electrical power system. LEC understands engine-driven generator sets and how to control them.
RICE power generation has great variety:
-
- • Different makes and sizes of engines running on different types of fuel
• Different kW ratings
• Different voltages
• Different applications: standby, prime power, utility parallel, single units, multiple units, etc.
• Different job sites which have site-specific requirements
- • Different makes and sizes of engines running on different types of fuel
- LEC offers paralleling switchgear and controls – primarily for the power generation industry. Primarily related to reciprocating internal combustion engines (RICE) driven generators. Does this sound like a niche business? It definitely is. LEC has an in-depth understanding of paralleling these type machines: with each other, with dissimilar machines, and against utility grids. Against “infinite” busses and with “finite” busses.
