CURRENT / VOLTAGE
1. There does not appear
2. Odorless
3. No sounds
4. Can be felt
5. Can cause death
BACKGROUND
Electric power has become a basic requirement for the public. Electricity contains the potential dangers that may threaten the safety of lives and property. Implementation of the electricity system there is need for government policy so as to reach all levels of society guaranteed their safety.
FIRES DUE TO ELECTRIC
1. The imposition of more
2. The connection is not perfect
3. Equipment is not standard
4. Limiting current is not appropriate
5. Insulation leakage
6. Static electricity
7. Clap
DIRECT CONTACT is the danger of touching the conductive parts that normally live.
INDIRECT TOUCH is the danger of touching the conductive parts which are normally not voltage, the voltage due to insulation failure.
HAZARD PROTECTION DIRECT TOUCH
Method :
1. Isolation of the active
2. Barrier or enclosure
3. Obstacles;
4. Safe distance or out of range
5. Residual current protective devices
6. Isolation of floorspace.
A TOUCH OF DANGER INDIRECT PROTECTION
Method :
1. TT or Grounding System Security (PP)
2. IT systems or conducting safety (HP)
3. TN or Neutral Grounding System Security (PNP)
Although there are gadgets and tools to make it easier for electricians to do their jobs. They still need to be very careful. Every year thousands of people are injured or killed from electrical shocks/contacts. They are exposed to dangers such as electric shock, electrocution, burns, fires, and explosions. The proper grounding of electrode system, conductors, equipment, and equipment conductors can help us in reducing the number of casualties. In order to understand grounding and bonding effectively, Electrician Online Courses will certainly help you in understanding the best way of grounding and bonding per the National Electrical Code (NEC) 2008 standards.
