ā€œIt was anticipated that fault currents were going to be high at this facility however when they were found to be >100kA this had implications for the specification of the generator tie in point. A new generator switchboard was required that could handle large fault currents. Using this information we could then confidently select, switchgear that was up to the job.ā€

Generator Feasibility Study

We conducted a generator feasibility study to determine if an emergency diesel generator could be connected to the existing electrical distribution network to ensure that pharmaceutical production could continue on the loss of mains power supply. The generator was required to synchronise with the mains. The feasibility study also included the front-end design of the upgraded network.

Project Details

Client:

Global Pharmaceutical

Location:

Southern Ireland

Premium Power Role:

Power System Consultants

Project Description

After conducting an extensive survey of the electrical distribution system, we developed a model of the facility to determine the anticipated network fault levels. The assessment highlighted the possibility of faults >100kA occurring. Fault levels greater than 100kA require a higher specification of switchgear that is capable of handling large fault currents to be installed, which increases the overall project cost.

Project Challenges

This pharmaceutical facility had recently introduced a new production process which required a reliable, mission critical electrical supply. The company had a robust electricity supply but due to the requirements of new pharmaceutical processes, it was determined that an even more reliable electricity supply was required. A full evaluation determine a suitable connection point that could be utilised for the emergency generator. The Client also required the installation to be conducted on a phased basis.

Project Outcomes

Our analysis concluded that a switchgear capable of operating during a fault of >100kA was needed, ensuring that the client purchased a switchgear capable of this specification.
