Power Distribution Design

Safe, Robust and Disruption-proof Power

Power distribution networks are lifelines to all your users. With the ever-increasing demand for power, your distribution network must perform efficiently now and over the long term. Designing and maintaining infrastructure to be robust and resilient in the face of systems and/or end-user changes can be a formidable task.

With our long track record of supporting utilities, industrial organizations, and government agencies, Casne has the knowledge and expertise to help. Whether it’s overhead power lines, transformers, substations or switchyards, our engineers ensure that every element performs optimally.

Our projects span:

  • Electrical specifications and selecting optimum electrical equipment
  • Power one-line diagrams
  • Panelboard schedules
  • Load flow analysis for all types of projects, including evaluating voltage drop, harmonic distortion, and power factor within the electrical system
  • Site and route optioneering
  • Smart grid development
  • Integrated power solutions
  • Scenario analysis for sustainable energy systems for new urban areas
  • Distribution from intermittent electricity production and renewable energy sources
  • Infrastructure development binding continents and facilitating intracontinental trade

Backup and Emergency Power Design

Minimal Downtime. Minimal Interruptions. High Reliability Power Backup.

Operationally critical facilities like yours cannot afford to have their power supply interrupted. When your power supply fails, standby or emergency power supplies must be ready to provide enough electricity to avoid downtime, loss of revenue and to protect both your assets and your employees. Also, whether you’re a hospital or a data center, you will be expected to comply with NFPA regulations such as the NFPA 110: Standard for Emergency and Standby Power Systems.

Our engineers know the ins and outs of these regulations and will design standby and emergency power systems that are reliable and provide long-lasting, safe power backup.

We design:

  • Emergency Systems
  • Legally-Required Standby Systems
  • Optional Standby Systems

We carry out comprehensive planning and testing before we design:

  • Examine existing and renovated units and protection concepts
  • Review building and electrical code requirements
  • Measure load flows and short-circuit currents in the distribution network and synchronization response
  • Analyze power supply networks and adopt protection procedures
  • Assess standby and emergency power supply availability
  • Assess control system response of generator system
  • Develop selective coordination and/or load-sharing plans for the systems
  • Supervise system installation and configuration
  • Verify load tests and warranty criteria

Power Studies

Arc Flash Analysis: Protect Your Personnel From Their Power Systems.

Electrical faults are unavoidable, no matter how safe your electrical power system. Work carried out on or near live equipment may lead to electrical faults, resulting in arc flashes. Employees exposed to arc flashes may face severe injuries or even death which is a concern for both your employees and plant management.

Casne recognizes the dangers that arc flashes can present and using the modeling tools available to us, we have helped many clients with these risks. Our goal is to coordinate the entire electrical system, including the protection device settings, as well as the calculation of the arc-flash incident energy at each piece of equipment. This allows you to select the correct personal protective equipment (PPE) for your employees in all situations.

When you contact us to carry out an arc flash analysis, we perform the following:

  • Field investigation to gather all necessary data
  • Carry out short-circuit calculation and protection coordination studies.
  • Provide a report that identifies the arc-flash energy available at each designated point
  • We are also able to produce the required labels upon your request
