Why energy is lost from power transmission cables?
Losses are mainly due to electrical resistance.
Why copper and aluminum are used in electrical cables?
Because they have low electrical resistance, good enough mechanical properties and aren't too expensive.
How is energy lost from power stations to homes?
The resistance of the cables that conduct the electric current away from the substations causes the cables to dissipate some of the electrical energy in the form of heat.
What is meggers?
A megger is an electrical instrument that is used to measure the resistance of insulation by applying a DC voltage to the conductor. One lead is connected to the conductor and the other lead is connected to ground. Safe insulation reading to ground should be above 2,000,000 ohms or 2 megs.
How do you remove electrical cables without damaging existing cables?
How do you remove electrical cables without damaging existing cables?"
In electrical installation why do you need to ensure the cables are not twisted or plaited?
Because it would affect the Cross sectional area of the conductor therefore altering the resistance.
Why. Are metals used for making electrical cables?
aluminium is used for making electrical cables as the metal do not melt easily
Why are electrical cables set to sag?
because of heat cables expand
What is a Continuity test on Electrical Cables?
Continuity of electrical cables must, because it is the process of inspection to found any discontinuity in the cable
Give you theory about electrical transmission without cables?
we can use the electromagnetic waves to transmit the electrical powers without the cables. But it is very difficult.
How is electrical energy fed into the house?
By cables.
What is electrical raceways?
an exposed conduit used for carrying electrical wires/cables
