Arc flash incidents can cause serious harm to electrical workers and damage valuable equipment on site. Our team of highly trained engineers are experienced in conducting Arc Flash Hazard Analysis, Arc Flash Studies, Arc Flash Mitigation solutions and specialised Arc Flash Training. We work with all size facilities across many industries to introduce and maintain Arc Flash safety.

Using proven software tools, our engineers calculate the prospective arc incident energy levels along electrical networks. Armed with this data, they assess the risks and identify the preventative and protective measures necessary to protect workers, electrical infrastructure and processes.

Isolating faulty components in a power system will help prevent serious power faults. The purpose of a protective device coordination (PDC) study is to model, assess and produce recommendations that will ensure as far as possible so that in the event of a fault the protection device closest will operate first, thus limiting downtime to this part of the system.

In order to ensure these protective devices operating in the correct sequence we look at the characteristic curves of breakers and fuses and ensure that they do not overlap inappropriately. Having completed this analysis we may propose adjustments to the settings of the circuit breakers and the types of fuses. It is possible at this stage we might include an electrical safety perspective.

PDC studies are an invaluable exercise in ensuring an electrical system operates to the required standard of reliability. Any electrical system will over time face new demands and requirements. Any significant changes to a site may impact on the behavior of protection coordination and need further analysis and adjustments.

EMC Arc Flash Study
Case study
EMC Corporation - Arc Flash Study
The Challenge

The EMC site is quite a large installation, with almost 300 boards to be assessed. A careful evaluation of current onsite documentation was required to ensure there were no gaps and the model could be built accurately. Much of the onsite protection equipment is old, requiring specialised power system modelling capabilities.

The Solution

We took all the information gathered to calculate the arc flash values in Cal/cm2 for every point in the network according to IEEE1584. This helped inform the client of the high arc flash areas of the plant, and where extra precautions were required when carrying out live work. We then provided recommendations on how to mitigate against these high levels.

Athlone Extrusions - Harmonic Distortion & Lower Energy Costs
The Challenge

As a leading thermoplastics manufacturer, Athlone Extrusions were concerned about downtime caused by electrical voltage harmonic distortion within their plant. This distortion was causing overheating of production equipment, cables and power components, such as transformers on the electrical network throughout the plant. The result was that the network circuit-breakers and fuses were tripping or blowing, leading to unplanned outages of plastics extrusion equipment. When this occurred, the molten plastic solidified within the extruder. The machinery then had to be dismantled and the plastic chiselled and extracted manually from the machine. Considerable time and cost was being lost in the process.

The Solution

We studied the plant network and found that the plastic extrusion equipment was generating a high level of voltage harmonic distortion. We designed a harmonic filtering solution that was installed at key locations within the plant. To design the best and most cost-effective solution, advanced power quality meters were installed and monitoring took place over some time. Our solution included individually designed harmonic filter banks, dimensioned to provide the necessary power factor correction and to reduce the harmonic distortion to levels acceptable for the sensitive production plant and to the electrical supply utility.

Parker Pneumatics
case study
Parker Pneumatics - Electrical Safety Programme
The Challenge

On this site, the client wished to achieve electrical safety compliance with national arc flash legislation while keeping with the company’s corporate health and safety requirements. The company wished to enhance awareness of arc flash hazard throughout their manufacturing facilities. Due to the age of the equipment on site, limited information was available, therefore we had to liaise with generator and busbar manufacturers directly. Generator reactance values and busbar impedances were critical in calculating the prospective arc incident energies on site.

The Solution

A detailed site survey was required to collect all network information. Following the site survey, the electrical distribution network was modelled before detailed prospective arc incident energy calculations were performed. The study involved an assessment of both medium-voltage and low-voltage equipment, which included an old overhead busbar system. In order to achieve the company’s gold standard accreditation, a full arc flash programme was implemented. This involved arc flash mitigation, labelling of all 3 phase equipment and arc flash awareness training for all technical staff – electrical and mechanical.

power quality
case study
Power Quality During Site Expansion
The Challenge

The size and complexity of the system required an in-depth interrogation of power quality and energy metering system, analysis of historical/future load, harmonic data, equipment types, and network configurations. This was necessary to create a software model of the upgraded site and predict harmonic emissions at the point of common coupling. When sizing and developing a specification for the passive filter design required, we had to account for changes in impedance (due to network switching), space constraints, and environmental conditions.

The Solution

We predicted levels of harmonic currents at the main MV distribution and specified a passive harmonic filter suitable for the level of predicted distortion, to mitigate against any adverse effects on the plant equipment, as well as to comply with future planning requirements for harmonic emissions set out by the utility provider. This resulted in high-cost savings coming from increased system performance and prevented penalties from utility providers, relating to low power factor and high harmonic contribution.
