MFT – Condenser Vacuum Low

Condenser Vacuum Very Low

Source : Pressure switch installed at condenser (500 mmHg abs)

Implication: Under turbine tripped condition and bypass in operation steam dumping continues at condenser which can result in pressurization. Under such poor vacuum conditions the condenser is not capable of dissipating the heat load with existing CW flow and with effect the temperature rises.

Action: MFT
