Disadvantages of low power factor

What are the disadvantages of low power factor?

The disadvantages of having low power factor are:

• Current drawn by the circuit will be high.
• Copper loss in the equipment will be high and hence, the efficiency of the equipment decreases.
• Equipment gets overheaded due to the copper loss, which in turn increases the stress on the insulation of the cable and makes it weak.
• As the current drawn by the circuit increases, the size of the conductor has to be increased to carry such current, which in turn increases the cost.
• Increases the KVA rating of the machine, which increases the size of the equipment, thereby increasing the cost.
• Voltage drop in the equipment will be increased, thereby affecting the voltage regulation of the equipment.
• Leads to decrease in the active power, which results in uneconomic operation of the equipment.
