(Solved) The permissible voltage drop from supply terminal to any point on the wiring system should not exceed
Question :
The permissible voltage drop from supply terminal to any point on the wiring system should not exceed
A. 4 % + 1 volt
B. 3 % + 1 volt
C. 2 % + 1 volt
D. 1 % + 1 volt
Answer : C. 2% + 1 Volt
As per Indian Electricity rule, voltage drop (in lightening circuit of) wiring system should not exceed 2% + 1 volt.
Note :
- Insulation resistance should be at least 1 Megaohm between two phases or phase and earth.
- Insulation of line should be designed in such a way that leakage current from line to earth should not be more than 1/5000 part or 0.02%.
