Support that continues after handover

Because I designed and documented the system, I can start from the drawings, I/O list and software files instead of from zero. Work carried out on each visit is recorded against the project, and later visits continue from the same record. Every change to the system stays traceable. 

• Commissioning support: Checks, tests and start-up on site.

• Fault finding: Diagnosis of electrical, control and communication faults.

• Backups: Program, SCADA and device configuration backups, with restore tests.

• Preventive inspection: Panel and network checks at agreed intervals.

• Upgrades and retrofits: New loads, feeders, protection devices, PLC or SCADA changes.

• Documentation updates: Drawings, labels, I/O list and software files updated after every change.

• Remote support: If offered.

1. Transport and position check: Enclosure, doors, gaskets and locks are inspected for damage, and layout, cable entry and earthing are verified.

2. Connection and torque check: Power and control connections, busbar joints and terminals are checked against the project, and labels are compared with the schematics.

3. Protection and metering check: Relay settings, transformer polarity and secondary circuit continuity.

4. Functional tests: Control, interlocking, signaling and communication are tested against agreed scenarios.

5. Energization and handover: Step-by-step energization, results recorded and the system handed to the operator.

The record made at the end of commissioning is the baseline for later maintenance.

Systems change over time: higher loads, new feeders, replaced protection devices, a new PLC or a SCADA connection. A retrofit starts with a review of the existing panel, drawings and software. The effect of the change on ratings, protection and communication is checked, and drawings, labels and software files are updated afterwards.
