One advantage that electronic governors have over mechanical ones is that electronic governors can?

The assertion that electronic governors can maintain pressure in all discharge lines if one line trips the governor highlights a key advantage of their design and functionality. Electronic governors offer a level of responsiveness and adaptability that mechanical governors typically cannot match.

When one discharge line experiences a drop in pressure or "trips," the electronic governor can instantly detect this change and adjust the throttle position accordingly to compensate. This ability to monitor and respond to multiple discharge lines simultaneously allows for a consistent pressure across all lines, enhancing the effectiveness of water delivery in emergency situations. By maintaining pressure, the electronic governor ensures that firefighters have access to the required water flow without interruptions, which is crucial during operations.

In contrast, mechanical governors rely on physical components that can be slower to react to changes in pressure. Factors such as friction and delays in mechanical movement limit their ability to adjust as quickly or accurately. Therefore, the capability of electronic governors to maintain consistent pressure across multiple discharge lines when a disturbance occurs is a significant benefit in scenarios where effective water management is vital.
