A block of flats is connected to a 240 V single-phase supply. Calculate The maximum permissible voltage drop between the supply and any point of consumption.
To calculate the maximum permissible voltage drop, we need to determine the acceptable voltage limit according to electrical standards and regulations.
In general, most electrical standards consider a maximum voltage drop of 5% as acceptable. This means that the voltage at any point of consumption should not drop more than 5% of the supply voltage.
To calculate the maximum permissible voltage drop, we use the formula:
Maximum Voltage Drop = 0.05 * Supply Voltage
In this case, the supply voltage is 240 V:
Maximum Voltage Drop = 0.05 * 240 V
Maximum Voltage Drop = 12 V
Therefore, the maximum permissible voltage drop between the supply and any point of consumption is 12 V.
