Electrical systems, instrumentation, and controls are involved in almost all projects undertaken by Perliter & Ingalsbe. These include mechanical projects, pump stations, wells, flow control facilities, pressure regulating stations, diesel generators, hydro power generators, reservoirs, tanks, administrative buildings and other similar public works facilities.
- Electrical Systems: Electrical systems may include the following.
- Electrical supply from service provider/utility company, involving low and medium voltage systems (4160VAC, 480VAC, 120/240VAC)
- Electrical power distribution system
- Electrical equipment, including switchgears, transformers, panelboards, and protective relays
- Lighting, receptacles, and switches
- Conduits and wires
- Instrumentation: Instrumentation is provided as required for each project and may include the following.
- Pressure gauges and switches
- Pressure and level transmitters
- Intrusion, proximity, limit, and position switches
- Motion sensors
- Solenoid valves
- Relays for variety of functions
- Push buttons, emergency stops, and reset buttons
- Temperature monitors, detectors, and switches
- Power monitors
