A Step-by-Step Guide to Arc Flash Analysis in Denmark

arc-flash-1

Electrical arcs arise when a gas is exposed to a voltage greater than the voltage it can block. When the voltage is high enough to ionize the air between the conductors, the arc begins. When a gas is ionized, it transforms into a great conductor, allowing electricity to flow and generating an “arc flash.” An arc fault is an unintentional electrical discharge.

  • High temperatures generate brilliant light and deafening noise in an arc flash.
  • A high-pressure wave capable of pushing molten metals and metal particles into the air is known as an arc blast.
  • Toxic vapors

Arc flash dangers may be extremely harmful to businesses and electrical infrastructure. Some of the commercial losses caused by arc flash threats are listed below:

  • Medical care, rehabilitation, worker’s compensation, accident investigation, and production downtime incur additional costs.
  • Legal fees, fines, insurance premiums, repair costs, and the expense of finding a replacement employee due to litigation.
  • A detrimental influence on the firm’s name and reputation.
  • Loss of business opportunities due to a history of accidents, which might result in the cancellation of an electrical license.

Arc Flashes Are Caused by the Following:

  • On a conductor, degraded insulation.
  • Human bodily parts that are visible
  • Human carelessness
  • Failure to properly maintain switches and circuit breakers
  • The water is quite near to the device.
  • Unplug any panels that are obstructing the route.
  • Conductors for high-voltage applications
  • Discharge of static voltage
  • Faulty tools and equipment

Arc Flash Evaluation Method:

Arc flash risks can occur whenever there is a high voltage or a low voltage with a high current switching.

Step 1: Determine the probability of an arc flash:

  • Gathering data, modelling the power system using software, analysing short circuits, investigating how overcurrent protection devices interact, analysing arc flashes, and assessing arc flashes are all part of an arc flash/fault study or analysis.
  • Assessing the chance of an arc flash injuring a worker

Step 2: Deal with the threat:

  • Employees are less likely to be wounded by arc flashes if they exclusively handle equipment that has been turned off.
  • Automated systems would be superior to manual ones.
  • To protect employee safety, place physical barriers between them and the operational equipment.

Step 3: Control of the process by engineers:

  • Reduce the fault current to lower the incident energy.
  • Arc flash detection and prevention systems
  • Controlling switches and remotes
  • Changes or enhancements to the switchboard
  • Non-moving circuit breakers
  • Insulation is required for bus bars.
  • Replace burned-out fuses with fresh ones.

Step 4: Administration-implemented controls:

  • Labeling switch rooms, plants, and other critical areas to detect where fluctuations in energy levels occur
  • Determining an arc’s perimeter
  • Making arc flash notes and diagrams.
  • Making certain that safe rules and procedures are in place to limit exposure
  • Using incident energy and PPE (Personal Protection Equipment) levels

Step 5: Personal protection equipment (PPE):

  • Even though personal protective equipment (PPE) is the least effective, it can reduce the severity of an accident but cannot prevent it. Personal protective equipment (PPE) is chosen based on the level of hazard.
