For a power system having induction motor loads, an overexcited synchronous motor is also attached. The induction motor will now operate at ________
lagging
leading
reduced power factor
increased power factor
lagging
The correct answer is A) lagging. In a power system with induction motor loads and an overexcited synchronous motor, the induction motor typically operates at a lagging power factor due to its reactive power absorption.
The correct answer is A) lagging. In a power system with induction motor loads and an overexcited synchronous motor, the induction motor typically operates at a lagging power factor due to its reactive power absorption.
Induction motors inherently consume reactive power, which results in a lagging power factor. The presence of an overexcited synchronous motor can help provide reactive power to the system, yet the induction motor remains a net consumer of reactive power, keeping its operation lagging.
Induction motors typically operate at a lagging power factor.
An overexcited synchronous motor supplies reactive power to the system.
Induction motors are robust and require minimal maintenance.
Synchronous motors can enhance overall system stability with proper reactive power management.
Induction motors can lead to higher losses at lagging power factors.
The requirement for reactive power from the supply may necessitate synchronous motors.
Industrial drives where induction motors are prevalent.
Power factor correction in industrial settings using synchronous motors.
The presence of an overexcited synchronous motor can potentially reduce the overall lagging power factor of the system but does not change the fact that induction motors operate at lagging.
Option B is incorrect because induction motors do not operate at leading power factors.
A is correct тАФ induction motors operate at a lagging power factor due to their nature of consuming reactive power.
Understand the relationship between power factor and reactive power in electrical machines, as this is crucial for both electrical engineering exams and practical applications.
