• Skilled technicians and well experienced engineers are prime requisite in successful installation of process instruments.
• GEPCO has such personnel along with latest testing equipment’s for installation of central control room, field mounted instruments, trunking, cabling/wiring, termination and tagging, piping and tubing for air supply and signal, loop checking & hooking up, testing, calibration etc.
Testing & Commissioning:-
• Global Electric Power Construction Company (GEPCO) has technocrats, equipment and knowhow for all pre- commissioning and routine testing of installed equipment /instruments, switchgears, control and automation system etc.
• Calibration of protective relays and measuring instruments. test of transformers , switchgear and MCC, CT, PT, protection and control relays.
• Instruments are Configured & calibrated using standard test equipment and testing methods and procedures.
• All circuitry and functionality tests are carried out.
Utilizing our experienced site engineering staff, GEPCO offers a competent
‘hands on’ test & commissioning service.
Testing & commissioning is probably the most fundamental part of any project. It is usually the last item on agenda & is the final proving, prior to handover to the client.
It is a demonstration, that the design intent, has successfully progressed, from paper through to reality & that the equipment & integrated schemes, safely operate as intended.
Both old & new equipment needs testing to provide client assurance that when there is a fault, not only will it clear safely, but also the equipment can contain it.
We are capable of carrying out most testing requirements.
Electrical tests can be classified as; Development tests, Type tests, Routine tests, Reliability tests, Commissioning tests. Reliability & Commissioning tests are the site tests & performed after installation of new electrical systems.
