Chapter 21, Problem 1SA

What is the purpose of an IVR?

To determine

The purpose of the IVR.

Answer to Problem 1SA

The two core purposes of the IVR are as follows:

• Voltage stabilisation.
• Reduce radio interference.

Explanation of Solution

The IVR stands for Instrument Voltage Regulator. The two core purposes of the IVR are as follows:

• The IVR stabilizes and limits the voltage to gauges. This leads to accurate gauge reading.
• A radio choke included in the IVR clears the radio interference caused due to the pulsating output of the IVR.

Conclusion:

Thus, the two core purposes of the IVR are as follows:

• Voltage stabilization.
• Reduce radio interference.
