Why Calculate and Use a Voltage Drop

His house Voltage drop refers to a drop in electrical current flowing through a circuit to prevent premature damage to everyday electrical appliances in offices and factories.

In Myanmar and internationally, there are already instructions for the maximum voltage drop allowed by the Electrical Code of Practice. In Myanmar, 5% (20v) voltage is allowed on 3phase, 400v. At 1phase, 230v allows 4% (9.2v) of output voltage. It is important to understand that no more than this is allowed. All electricity operators in Myanmar must abide by this rule.

If the voltage drops too much, the wires connected to the performance of the electrical devices may overheat and be damaged. The easiest way to reduce the voltage drop is to increase the diameter of the conductor between the source and the load.
