Onsite Engineering Support
We can provide onsite engineering presence at our client’s facilities; this includes project or multiyear engineering presence for our larger clients who have multiple simultaneous projects.
We can review our client’s electrical infrastructure to determine obsolescence, equipment age and recommended maintenance intervals as well as replacement options.
We can review the equipment and the criticality of the electrical equipment to help develop a preventative maintenance program.
Feasibility and Scoping Studies
When expanding or replacing complex electrical infrastructure there is often numerous solutions available, different solutions can vary in price and performance, most of our clients don’t have a one size fits all solution and its critical to understand the clients application and needs and develop a solution that is optimized to the customers needs.
Front End Engineering (FEED)
To develop a scope and determine the type of equipment to specify will require some preliminary engineering, this often includes power system studies and drawings. This initial investment at the start of the project can reduce the unknowns that can lead to scope drift and overspends later in the project.
It is critical to communicate requirements of the client and the application by developing a detailed scope this initial investment reduces uncertainly or ambiguity.
Developing a clear bid document is critical to ensure that all bidders understand the requirements and are submitting comparable bids.
Complex electrical projects can require several contractors to implement different phases of the project, we can manage the communication between the different contractors and coordinate the all aspects from site mobilization, orientations, scheduling and demobilization.
From the project charter stage to project closeout, we assist our client in developing budgets to forecasting, scheduling, contractor mobilization and onsite contractor support, commission and start-up planning, execution planning.
Witnessing Factory & Site Acceptable Testing (FAT/SAT)
To ensure manufactured equipment meets the specifications, standards, and design, we will attend on clients' behalf at the vendor's factory to witness the Factory Acceptance Testing and participate in onsite to witness the site acceptance testing during commissioning.
Commissioning & Start Up
We will plan the commissioning and start up activities with the vendor to ensure proper document handoff to the client in preparation for energization. This process ensures that deficiencies during construction is addressed prior to the equipment being handed off to the site.
Power System Studies
Electrical Distribution Modelling using ETAP
Short Circuit Studies and Analyses
For safety and reliability its critical to determine if the electrical distribution can handle a fault, equipment such as breakers are designed to handle a maximum fault current which is indicated on the nameplate, by performing a short circuit study the fault current can be calculated and the equipment evaluated to determine if it will clear the fault.
Arc Flash Studies
Arc Flash studies are a useful tool in electrical safety; arc flash incidents are a well-documented hazard; however, the subject itself is often misunderstood, leading to contradictory approaches and confusion. We review and model the client's electrical distribution to calculate the arc flash incident energy, providing arc flash labels, and issue a report with recommendations to reduce or mitigate the hazard using the latest standards.
Protection Device Coordination
When expanding a facility or optimizing the electrical distribution of an existing system, a protective device coordination study is useful for ensuring a reliable and safe system. When a fault occurs on a system a breaker will trip, the goal of a well-coordinated system is that the breaker closest to the fault trip without causing other breakers upstream to trip, which would cause a more extensive outage. A coordination study can cover all equipment from the utility-owned protection down to individual panels.
Load Flow Studies
A load flow study is useful for determining the electrical distribution capacity when expanding. It is essential to understand the effects of adding additional load to the existing system to ensure that voltage drop and transformer loading are acceptable.
Power Factor Correction
A glance of the utility bills is often the first indication of poor power factor; inductive loads such as motors will drop the power factor; when the power factor drops below certain thresholds, the utility will impose a power factor penalty. By studying different power factor correction options, the cost of correcting the power factor can be considered to determine ROI.
Ground Grid Design & Step and Touch
Modelling the electrical distribution in combination with power quality recording is a useful tool in identifying the sources of power quality issues.
Voltage Drop & Motor Starting
Both motor starting and voltage drop can be modelled to allow options to be developed for reconfiguring the electrical distribution to accommodate new loads.
Electrical systems are either solidly grounded, ungrounded or impedance grounded, we can review the system to determine if an improved grounding system can be used to increase safety and reliability.
Electrical Single Lines
We will review your existing or new facility and develop a site-wide single drawing that covers all areas of the electrical distribution.
Complete customer owned substation designs, from 480V up to 69kV.
Protection, Switchgear and MCC Design
We develop a detailed drawing package to submit to equipment vendors and construction contractors.
Arc Flash Mitigation
As a result of an arc flash study, there can be equipment that has high incident energy; there are many solutions that can reduce arc flash energy or methods to reduce the exposure to equipment operators. We can explore these options and design an arc flash solution that fits the specific needs of the client.
Our electrical drafters work with our professional engineers to develop drawings for our clients.
Determine the sites protective relaying requirements to determine the most suitable equipment model and protection elements for protecting the client’s electrical distribution.
