Methods for determining power cable faultsGenerally speaking, the power cable is mainly broken fault, grounding or short circuit fault, broken wire and ground fault and flashover fault, and so on. We can determine the type of fault in the power cable according to some of the following methods. Here we need to use the insulation resistance table, w...
Factors affecting the carrying capacity of copper cables1 Ambient Temperature
The ambient temperature value used is the temperature of the surrounding medium when the cable or conductor is not loaded.
2 Soil Thermal Resistivity
For cables laid in the ground, where the actual soil thermal resistivity is higher than 2.5 K.m / W, the carrying capac...

Definition of ElectricityThe electric power P is equal to the energy consumption E divided by the consumption time t:
P is the electric power in watts (W).
E is the energy consumption in joule (J).
t is the time in seconds (s).Example
Find the electric power of an electrical circuit that consumes 120 joules for 20 seconds.
Solution:
E = 120J
t...
