Malicious regulation of power supply and its prevention

Control of power supply damage and its prevention

Computers can have various problems related to power supply. Irregular supply of electricity is one of the problems related to computer power supply. Besides, not having proper voltage, frequent power supply, power return in shortest time interval, lack of earthing, fault in power supply unit, heating of internal parts of power supply unit, not getting proper voltage and signal at output power supply unit switch Not working mode etc. are some of the harmful regulators of power supply. All these problems and solutions are described below --

(a) Voltage problem : Damage to computers and other electrical appliances due to high voltage is a regular occurrence in our country. A voltage stabilizer can be used to avoid this condition. Many times when the voltage is much lower than required, any electrical appliance used in the home cannot be operated. In this case, the computer should be turned off.

(b) Sudden power outage : Load shedding is a common phenomenon in our country. If the power suddenly goes off while the computer is on, the unprotected part of the work will be destroyed. Temporary or permanent problems may occur in the operating system. The hard disk is the most damaged if the power goes out suddenly. It reduces its lifespan. To solve this problem, at least 15 minutes of power supply should be used with UPS.

(c) Short Power Outage: A short power outage usually occurs within one to two seconds. In this case, the time interval between power outages and power outages is so short that the user will realize that a power outage has occurred after the computer starts the process of shutting down and restarting. This is a serious problem for computers. Due to this, almost all devices including processor, RAM, hard disk can be damaged. The solution in this case is to use a suitable UPS.

(d) Earthing problem: Most of the houses in our country do not have earthing system for electricity. In this case, computer users can feel a small amount of electricity when they touch the metal part of the computer. As a result, the computer user is in a kind of panic. Provision of earthing for electricity in the house and use of sandals or shoes made of non-conductive material on the feet.

(e) Problems with Power Supply Unit: Using low power Power Supply Unit, Faulty Power Supply Unit, Overheating of internal parts of Power Supply Unit, Not getting proper voltage and signal at output, Power Supply Unit not working in switch mode. etc. How many problems of power supply unit.
