Describe the operational procedures for handling a 'loss of vacuum' event in a geothermal power plant's condenser.

A loss of vacuum in a geothermal power plant's condenser is a serious event that can lead to reduced power output and potential equipment damage, requiring immediate and carefully coordinated operational procedures. The initial action is to immediately confirm the loss of vacuum. This involves verifying the pressure readings from multiple pressure sensors in the condenser to ensure that the loss of vacuum is genuine and not a sensor malfunction. If a loss of vacuum is confirmed, the turbine should be tripped, which means shutting down the turbine to prevent damage. This is typically done automatically by the pl....
