Question 1 of 31048

In general, what type of starter would be used to connect polyphase induction motors to full line voltage at the instant of start-up?

🔍 Key Concepts

• Polyphase induction motor starting methods and how they affect line current and torque • Meaning of full line voltage at the instant of start-up versus reduced-voltage starting • Typical use and function of primary-resistor, compensator, autotransformer, and across-the-line starters

💭 Think About

• Which starter type applies the same voltage as the supply directly to the motor terminals, without intentional reduction at start? • For each option, ask yourself: does this method try to limit inrush current by reducing voltage, or does it accept high starting current for simplicity? • Think about small/medium motors in simple applications: what is the most straightforward, lowest-complexity way to connect the motor to the supply?

✅ Before You Answer

• Verify which methods are specifically classified as reduced-voltage starters (they are NOT what the question is asking for). • Check the definition of across-the-line starting in your electrical or motor control references and how it relates to full line voltage. • Confirm that primary-resistor, compensator, and autotransformer types all introduce something between the line and the motor to drop initial voltage and current.
