1.	the maximum permissible voltage drop in a power industrial circuit should not be more than of the declared supply voltage
Answer» <p>Voltage drops occur throughout the distribution network. However, it is necessary to regulate the voltage in order to ensure that these drops stay within a permissible range. High voltage drops, below the permissible level, can have many negative consequences. These result in an increase in the system maintenance cost and a decrease in the safety and performance of the network. Operating electrical equipment below its rated voltage can be dangerous as well as reducing the expected lifetime of the equipment. When inductive loads are operated below their rated voltage, they tend to overheat and consume more power. Resistive loads which are operated at a too low voltage will not be able to produce the desired output. Reducing the voltage by 10% will reduce the power output by 19%, since power output correlates to the voltage squared. A reduction in the network voltage can cause lights to flicker when other appliances are turned on.</p>
