Why are arcing faults dangerous?
The arcing faults are caused due to the equipment failures, improper placing of tools, improper use of equipment and the conduction of electrical current due to the foreign particles present in the air. If the arcing currents are at higher levels, these can cause fires and injuries. These arcs can be extremely high energy or low energy arcs, extreme one damages the equipment resulting in fragmented metal to fly in all directions, whereas the low energy one cause blasts in atmosphere by releasing explosive gases, combustible dusts and vapors.
How does ohms law work?
Ohm’s law states that one volt will cause to current flow of one ampere through one ohm resistance. Therefore the voltage is the important factor that determines the current flow through a body resistance. Basically, the human body is also a resistor and its resistance is measured in ohms. Human body resistance is not fixed, but it varies from time to time and person to person. Human body resistance of various parts is

How does electrical arc affect the body?
Most of the times electrical arc releases thermal radiations. Due to this thermal energy person get injured where the part of the body exposed to it. The degree of injury depends on the skin exposed, skin color, type of clothing wear, etc. To avoid the chances of getting injuries person must wear proper clothes, should maintain work distance and other over current protections.
What happens when an electric shock occurs?
This electric shock happens when. The body get contact with conductors in an energized circuit. The body provides a path between conductor of an energized circuit and the ground. The body gets contact with a metallic part that has contact with energized wire.
What is “Exposed”?
Exposed, simply speaking, is when a person can inadvertently make contact with an energized conductor or circuit part. In it’s definition, a part is considered exposed if it is not properly guarded, isolated, or insulated. So if you can touch a bare part, then it’s considered exposed. Some common exposures to look for include:
How to determine if a part is exposed?
For times when a closer look is required, we use an articulated test finger. If the test finger makes it past a guard or through an enclosure opening and touches a circuit part, then the part is considered exposed. In these cases, we often re-engineer the guard or enclosure to properly eliminate the hazard exposure.
What does it mean when you can touch a bare part?
So if you can touch a bare part, then it’s considered exposed. Some common exposures to look for include:
Is 1000 V a hazard?
The voltage is high enough to arc across an air gap, and you don’t have to make contact for it to be a hazard. In this case there are safe approach distances. Proper enclosures that surround the conductors and keep people far enough away are sufficient to guard against the hazard.
Safe distance from electric lines
It is obvious that electric overhead lines should not be allowed in a place where the public or public vehicles have to pass through for most of the time and not at such a low or unsafe distance (clearance above ground) so that chances of touching the lines may increase.
Capacity and protection of conductors, joints and connections
All apparatus and conductors should be of sufficient size and strength. They should be covered with insulating material and placed or enclosed as to prevent danger.
Means of cutting protection
Danger from excess current due to overload or short-circuit should be prevented by providing: 1. fuses 2. circuit-breakers or 3. thermal protection.
Earth insulation and continuity tests
When electric current passes through its expected distance (load) path. Its energy is utilized in heating , rotating or doing the required function. But when due to insulation failure, breaking, opening or loosening of conductor or directly touching to any metal part, tool or human body, the current passes through the line of least resistance i.e.
Ear-thing standards
Ear-thing means a low impedance return path of the fault current. Actually the earth, now, rarely serves as a part of the return circuit but is being used mainly for fixing the voltage of system neutrals. The earth connection improves service continuity and avoids damage to equipment and danger to human lives.
Protection against Surges and Voltage Fluctuation
When equipment is switched on, momentarily initially excessive currents are known as current surges.
Voltage fluctuation
This is a common phenomenon. Supply voltage goes down resulting in reducing speeds of fans, motors, machines etc. Again it comes and stabilizes the condition.
How to turn off electrical circuits in water?
If electrical circuits and electrical equipment have gotten wet or are in or near water, turn off the power at the main breaker or fuse on the service panel. Do not enter standing water to access the main power switch. Call an electrician to turn it off.
What to do after a hurricane?
Stay safe after a hurricane, flood or other natural disaster. NEVER touch a fallen power line. Do not drive through standing water if downed power lines are in the water. If you believe someone has had electric shock, call or have someone else call 911 or emergency medical help. On This Page.
What to do if you see sparks on your power?
If you see frayed wiring or sparks when you restore power, or if there is an odor of something burning but no visible fire, you should immediately shut off the electrical system at the main circuit breaker. Consult your utility company about using electrical equipment, including power generators.
What to do if you are faint and you are in shock?
If the person is faint or pale or shows other signs of shock, lay him or her down with the head slightly lower than the trunk of the body and the legs elevated.
What to do if you can't get electricity?
Once the person is free of the source of electricity, check the person’s breathing and pulse.
What to do if power line falls?
Call the power company to report fallen power lines. Avoid contact with overhead power lines during cleanup and other activities. Do not drive through standing water if downed power lines are in the water. If a power line falls across your car while you are driving, stay inside the vehicle and continue to drive away from the line.
