This type of system is not recommended because it can lead to a number of problems, including:<\/p>\n<ul>\n<li>Insulation being overstressed due to over voltages. When there is an overvoltage on an ungrounded neutral system, the current will flow through the insulation of the conductors. This can cause the insulation to overheat and fail.<\/li>\n<li>Insulation overstress may lead to failure and subsequent phase to phase faults. If the insulation of the conductors fails, it can cause a phase to phase fault. This is a type of fault in which two phases of the electrical system come into contact with each other. Phase to phase faults can cause serious damage to the electrical system and can even lead to fires.<\/li>\n<li>Being inadequately protected against ground fault. An ungrounded neutral system is not adequately protected against ground faults. This means that if there is a ground fault, the current will not flow through the ground wire and the fault will not be detected. This can lead to serious damage to the electrical system and can even lead to fires.<\/li>\n<\/ul>\n<p>For these reasons, ungrounded neutral transmission systems are not recommended.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>[amp_mcq option1=&#8221;insulation being overstressed due to over voltages&#8221;
