5.3.4 The monitoring station shall be designed to meet the requirements as the followings.
The station shall be set in the vicinity of the monitoring instrumentand at the location with good accessibility，illumination andventilation and without interference，as well as with adequateworking space and stable power supply.The station shall not bearranged in the vicinity of the equipment with strong electromagneticinterference，but shall have good earthing.Where the station is set inthe open air or it is likely to suffer from water drip，proper protectivemeasures shall be taken.
5.3.5 The monitoring management station shall be designed to meet the following requirements.
（1）The station may be arranged either in a comparatively good workenvironment such as the dam crest，dam abutments or powerhouse atthe dam toe，or at the power plant administrative zone far away fromthe site.In the station，there shall be necessary space for arrangementof the equipment and for work，good illumination and ventilationconditions.In addition，it shall be provided with stable and reliablepower supply and grounding devices so as to meet the environmentalrequirement for normal operation of the indoor equipment.
