A synchronous phase-modifier is used to _________________________.
improve system power factor
balance system voltage (transmission line)
control self (Synchronous motor) reactive power
control active power of load connected in the system
balance system voltage (transmission line)
A synchronous phase-modifier is used to balance the system voltage in transmission lines, ensuring that voltage levels remain consistent and within acceptable limits. This helps to improve the overall stability and efficiency of the electrical power system.

The synchronous phase-modifier operates by adjusting the phase angle of the voltage in the system, which effectively stabilizes the voltage across transmission lines. It achieves this by supplying or absorbing reactive power, thus maintaining the desired voltage levels and enhancing the capacity of the transmission system.
Synchronous phase-modifiers can regulate voltage by controlling reactive power.
They play a critical role in long-distance transmission systems.
Improved voltage stability in transmission systems.
Increased efficiency of power delivery.
Complex control systems required for operation.
High initial installation costs.
Used in large electrical networks to maintain voltage levels.
Applied in industries with variable loads to stabilize power supply.
Standard specification values depend on system ratings and operating conditions.
Option A is incorrect because improving power factor relates to reducing reactive power loss, not specifically balancing voltage.
B is correct тАФ Synchronous phase-modifiers are specifically designed to balance the voltage in transmission lines.
Understand the relationship between reactive power and voltage stability in electrical systems for better problem-solving in exams.
