Electricity is an important source of power which finds wide-scale application in our day to day lives. It has become a part and parcel of human life. If it is not used properly and carefully it can be dangerous as well as life threating. It can cause serious injury or even death on being used carelessly. But with the aid of electrical repair and maintenance such dangerous and serious situations are made much less adverse.
This is because the electrical repair and maintenance system helps to kept electricity under continuous vigilance. According to statistics for the period 2003 to 2015 around 142 workers have died as a result of coming in contact with electricity, accounting on average, 11 worker deaths per year, around 87% of these deaths, which accounts for 124 deaths, have happened during installing the electrical infrastructure. The risks involved and associated with the use of electricity can be reduced with proper communication of these control measures. Therefore, electrical repair and maintenance activities as a support system for maintaining electricity standards.
How to Mitigate the Risks If Supply Is at High Voltage?
If an electricity entity is allowed to supply electricity to the customer at high voltage, then the agreed voltage is considered to be the standard voltage for the supply. Most power supply units in Australia functions on a nominal 240-volt system, with a lower working limit of 230 volts. If there are changes of the voltage at customer’s consumer terminals, then the supply of electricity by the electric supply unit must be maintained at this changed standard voltage.
How to Mitigate the Risks If Supply Is at Low Voltage?
For supply at low voltage, the electricity for general supply must be alternating current, having a nominal frequency of 50Hz. The standard voltage for electricity supplied at low voltage from a 3-phase system must be between a phase conductor and the neutral conductor at 240 voltage and between 2 phase conductors at 415 voltage. For single- phase systems, it must be between a phase conductor and the neutral conductor, valued at 240 voltage, and also between the two-phase conductors at 480 voltage.
These voltage limits should be checked and maintained on a regular basis to understand the overutilization or underutilization of the electrical systems. This can be done by undertaking regular electrical repair and maintenance through a competent professional Different method for Electrical Repairs and Maintenance.
1) Safety Switches
Residual-current devices, also known as safety switches are a form of electrical safety device which acts by immediately switching off the electric supply on detection of electricity leakage at dangerous levels. It helps in avoiding damage to workers and also the other equipment being used.
An RCD is a must have in cases where the electrical equipment used at an individual’s workplace is supplied with electricity via an electrical socket, a form of plug-in electrical equipment. It is also to be used when the equipment is used under conditions which are liable to cause damage or reduce the life span.
Regular inspection and testing of the electrical connections help in identifying damage, wear, and other electrical faults. Detection of many electrical defects such as damaged cords can be undertaken by regular inspection and testing. This makes the detection of such electrical faults easier even when they are not visible to the naked layman’s eye.
3) Professional Help
Professional help should be sought during the time of inspections and testing. He must be a licensed or registered electrician or electrical inspector.
Therefore, electrical repair and maintenance activities as a mainstay for the entire central electricity providing system across Australia. And we should be very careful with this helpful yet dangerous source of power.
