Functional Protection Features

The GPU2000R integrates several critical protection functions into a single unit to safeguard the generator stator and rotor:

• Overcurrent Protection: Monitors phase currents to prevent damage from short circuits or sustained overloads.

• Ground Fault Sensing: Highly sensitive detection of insulation failure between the windings and the machine frame (ground).

• Industrial Control Design: Specifically built to withstand the electromagnetic interference (EMI) and vibration found in industrial engine rooms and power plants.

• High-Mass Construction: The 23-lb weight reflects its extensive internal shielding and heavy-duty transformer components, ensuring thermal stability and measurement accuracy during fault events.
