Case Studies - PAC Calibration
Calibration Support – Power Station
Calibration Support – Power Station Northern Ireland
Objective
The remit of the work was to support the client’s existing C&I on-site team with the calibration of the plant’s temperature indicators and transmitters, and pressure indicators, transmitters, and switches. The PAC Calibration team tested the accuracy of plant instrumentation so that it operated within the specifications of plant operations.
Process
After site induction, one of the PAC team was trained in the process required to obtain Permits to Work and was issued with keys for the client’s lock-off system. This allowed the PAC Calibration team to carry out work without requiring constant supervision by the client’s staff. Due to the nature of the work, some live voltage testing was required to test the 4-20ma measurement loops and plant pressure switches.
Units were tested using UKAS traceable equipment, with the results noted and recorded on PAC’s database and the calibration certificates. Any anomalies were reported to the client’s engineering department and adjustments were made, as required. In addition, any faulty instrumentation discovered was reported and replaced by our team.
At the end of the outage PAC Calibration issued the relevant certification to the client.
Outcome
A representative from the client said:
“PAC Calibration have completed outage calibrations for us on a number of occasions, and we’ve found the service very professional. With the minimum of assistance they were able to safely complete an extensive list of calibrations, and highlight equipment that needed adjustment. Their assistance during an outage allows station staff to concentrate on other work going on.”
“PAC have on occasion been called on to provide short-notice support and have always been able to meet our needs. They also provide calibration certificates that help us to meet our quality system certification. I can whole-heartedly recommend their service.”
