The Value of Arc Flash Risk Assessment and Prevention Strategies in Denmark

arc-flash-2

When a gas is exposed to a voltage that exceeds its capacity to block, electrical arcs can form. An arc happens when the voltage is high enough to ionize the air between the conductors. When ions are introduced into the air, it transforms into a great electrical conductor. Air ionization produces a current that heats and lights the air. Because of the heat, the ionized air ascends, generating an arch-shaped stream. As a result, the phenomenon is called an arc current. Temperatures in an arc flash can reach 20,000 degrees Celsius.

Arc flash risks may harm both people and property. Among the commercial advantages of arc in flash are:

  • Medical care, rehabilitation, worker compensation, the cost of investigating the occurrence, and productivity losses are all direct expenditures.
  • Legal and judgement fees, litigation expenditures, penalties, insurance premiums, repair charges, and the cost of hiring a new employee are examples of indirect costs.
  • When unfavorable events occur, your reputation suffers, finding work becomes more difficult, and you may even face criminal charges.
  • Most customers will not do business with a company that has a high rate of accidents, which can result in lost income and the loss of an electrical contractor’s license.
  • Errors involving arcs Flash leave a lasting impact, which can lead to missed chances and wasted money.

Arc Flash Threats Come From:

  • Using the wrong surface with the probe
  • Inappropriate tools, installation, and work methods
  • Using low-quality electrical components.
  • Damaged insulation or equipment gaps
  • Remove panel interference
  • Dust or corrosion on electrical equipment
  • Failure to properly maintain circuit breakers and switches
  • Live components that are exposed or frayed connections
  • High-voltage cables or a steady-state power supply
  • Moisture in electrical equipment

Methods for Minimizing the Risk of Arc Flashes Include:

Putting an end to electrical components: 

It reduces potential dangers to the greatest extent feasible. Work should not be done on live equipment, and great care should be taken while testing it after it has been de-energized or before it is re-energized. Remote tracking is utilized to keep circuit breakers away from potentially dangerous arc flash limits. 

Utilize low-risk technologies: 

To evaluate the hazards of short circuits and how protective devices interact with one another, arc flash analysis and power system studies are performed. To safeguard people and property, choose low-risk alternatives such as remote rack equipment. 

Electrical and control systems must be modified: 

Ascertain that adequate PPE (personal protective equipment) is available based on the arc flash’s hazard level. Engineering equipment and methods are being modified to make them safer. To limit the amount of energy that may travel through, circuit breakers and energy distribution systems are built. 

Reduce the amount of accessible fault current:

Industries will be able to control the amount of available fault current with non-current limiting breakers. These products can be used with an open tie during maintenance. The opening connection between dual power feeds reduces arc flash risks during maintenance by lowering the available fault current. Current-limiting reactors can be used to stop the flow of electricity, so preventing arcing. 

Change the blast’s power: 

Encourage the use of materials that are resistant to arcs. Arc-resistant switchgear absorbs the energy and heat created by arc flashes and distributes it through ducts to an unoccupied area. This is done with sealed joints, top pressure release vents, and stronger hinges. CareLabs offers a wide range of arc flash research and analysis services.
