Electrical and Instrumentation

Electrical works include the installation of electrical systems throughout the facility which include: conduit and cable tray installation, cathodic protection, cabling, grounding systems, duct bank installation, electric motors and generators, switchgear installation, relays and breakers, transformer and junction box installation, motor control centre and control panels, as well as lighting and communication systems.
Once the electrical systems are in place, the installation of instruments such as, transmitters and transducers, control valves and switches, safety relief valves, analysers and indicators can take place. All instruments undergo a series of testing and calibration as required by the main contractor before installation.
After completing the installation of instruments, a loop check is performed. This quality review consists of testing and identifying faults or failures in the entire system, which interconnects different instruments and processes.
