When gas is exposed to voltages higher than its insulating properties, arcing can occur. An arc is formed when the voltage is sufficient to ionize the air between the conductors. Ionized air becomes an excellent conductor and conducts electricity. The ionization of the air creates electrical currents that produce heat and blinding light. This heat causes the ionized air to rise, creating an arcing flow, hence the name of the phenomenon. Arc flash can produce temperatures up to 20,000 degrees Celsius.

Electrical arc hazards endanger people and property. Commercial effects of arc flash include:

Overhead costs include litigation costs, court costs, litigation costs, fines, insurance premiums, repair costs, and replacement labor costs.
Your personal reputation, competitiveness in the labor market and potential criminal prosecution may be adversely affected.
Most customers will reject companies with high accident rates, resulting in lost business opportunities and potential revocation of electrical contractor licenses.
Accidents with electrical circuits Lightning tends to make an impression, resulting in missed opportunities and wasted income.

Arc Flash Hazard Causes:

Using the incorrect surface for the test probe
Inadequate installation, work techniques, and tools
Use defective electrical components.
Equipment holes or damage to the insulation.
Remove any panel interference.
Either rust or dust on electrical equipment.
Improper maintenance of the circuit breakers and switches.
Live components exposed or a frayed connection.
Wires with a high voltage or a steady power supply.
Moisture in electrical equipment

How to Reduce the Hazard of Arc Flash:

De-energize Electrical Components:

Minimize potential hazards as much as possible. Avoid working with equipment in service and take unusual care when testing or reconnecting equipment. The circuit breaker is kept away from arc boundaries that could threaten the operator using remote tracking technology.

Use of Low-Risk Techniques:

Arc analysis and power system surveys are performed to detect hazards associated with short circuits and protective device adjustments. Leverage low-threat solutions such as: B. Remote rack equipment for protecting people and property.

Electrical and Control System Redesign:

Ensure access to PPE (Personal Protective Equipment) required for Arc Flash Hazard Category. Technical equipment and procedures have been modified to reduce hazards. The circuit breaker and distribution system are designed to limit incident energy.

Reduced Available Fault Current:

The non-current limiting circuit breaker helps the industry reduce the available fault current. These devices can be used with an open connection for maintenance. Opening a connection between two power supplies during maintenance reduces the available fault current and thus reduces the threat of arc flash. A current limiting reactor can be used to create a bottleneck in current flow, effectively preventing current flow during an arc fault.

Change Blaster Energy:

Accelerate Arc Resistant Materials. Arc-resistant switchgear uses sealed connections, top pressure relief vents, and reinforced hinges to channel arc energy and heat into open areas. CareLabs perform extensive arc flash analysis. Arc flash hazards are assessed by experts to update safety programs. CareLabs can find and implement the latest strategies to avoid arc flash risks.

CareLabs can research and implement cutting-edge technology to reduce arc flash risk. The Nursing Institute uses ETAP software for research and analysis. We employ crews in multiple locations to ensure that our knowledge is available on a regular and emergency basis. We quickly became ISO 9001:2008 certified and have a loyal customer base, Bangkok, Chiang Mai, Samut Prakan, Udon Thani, and Nonthaburi are cities in Thailand.
