Due to the installation of ventilation fan yesterday, the PM for water treatment plant motor PM is done today. It is required to check the on load current, insulation resistance, bearing vibration and body temperature.

Besides the PMs, the condenser fan motor for air condition 1B at center control room also not function. Hence, we need to go to do the checking.

After the adjustment and install the new motor, both the condenser is functioning.
