Earth has the constant potential so we take it as reference.but in steo & touch voltage we use to calculate voltage of ground in 30 inch. How it is possible if no current can flow through ground?
Latest Answer : Neutral is the line provided for completing the circuit path in an AC circuit.Phase and Neutral is a combination like Positive and Negative.Whereas Earth is is connected to the body/cover of electric instruments at one end and is actually burried into ...
How much voltage is present in neutral resistance?and how much voltage is present in earth resistance
1. what is the different between CGS system and MKS system? 2. When we connect the capacitor Banks in Series with the circuit 3. What is the difference between Earthing & grounding 4. how much voltage
generally we are using 4 core or 3.5 core cable for power supply ,in this practice we are connecting three different phase R,Y,B and Neutral to our 4 core or 3.5 core cable,but for our termination conveniences
Latest Answer : The generation of heat is because of the transfer of power between the three phases due to the inductive behaviour of the lines.If the cables had beem properly transposed the heating could have benn avoidede which has been done in an ordinary cable. ...
Latest Answer : Insualtion resistance(IR) value of a motor does not depend upon rating(i.e. KW). It is depend upon Voltage label in which it applied.There is a example:If V=415v then IR should be min. 1.415 MohmAnd if V=6.6kv IR should be min. 7.6 Mohm ...
Latest Answer : Earthing of a system is to protect the system from high surge current/voltage due to lighening while neutral provides return path to the current flowing in the tranmission line. ...
Why do we use neutral ct in a transformer?
Latest Answer : The protection engineers use the neutral CT to detect the actual E/F. ...
