to the apparatus which they are to protect. It is advisable to 

 enclose them in compartments, like the transformers, and pro- 

 vision should be made so that they can be securely anchored. 

 They should be installed at a distance of approximately half their 

 diameter from any iron or steel structure so as to prevent any 

 heating of this and consequently increased losses. 



Switchboards. The different pieces of apparatus comprising 

 the switching equipment are distributed on the various floors 

 in the switch section of the station, each story being partitioned 

 to suit the various purposes. The operating room with the con- 

 trol switchboard is generally located on the second floor and in 

 such a position that the operator may have an unobstructed view 

 of the station and be able to readily communicate with the tur- 

 bine operators. A balcony, somewhat overhanging the generator 

 room in front of the switchboard, is often provided, or the operat- 

 ing room is built with a curved front wall extending out over 

 the generator room.
