BRINE TANK LOAD TEST TESTING AND ADJUSTING amount of salt) and maximum electrode immersion.  (Greatest possible electrode area in the liquid.) For any current reading, the power output of a 3- phase   generator   can   be   calculated   using   the following formula: kW= E x I x 1.73 1.000 X P.F. Where:  kW = Kilowatt output E   = Voltage (average of 3 lines) I     = Amperes (average of 3 lines) PF = Power Factor A brine tank is a 1.0 power factor load. WARNING Rated generator kW occurs at 0.8 PF. Therefore,  to  obtain  generator  rated  kW  the  line current should be 80% of the nameplate ampere rating  of  the  generator.      Operation  at  full  rated current would result in a 25% overload. PORTABILITY The brine tank can be made portable by placing it  on  a  small  steel  trailer  as  seen  in  the  picture. The trailer should be equipped with a trailer jack on each corner to enable the tank to be leveled. SAFETY The  brine  tank  test  should  not  be  used  for  any generator   above   480   volts.      If   the   generator voltage  is  greater,  use  reduction  transformers. Avoid any possible flash over between electrodes and tank. Be sure the tank or any of its metallic support is connected to a good earth ground. The    tank    should    be    equipped    with    overflow outlets  to  prevent  the  boiling  water  from  spilling over the top of the tank. Each opening should be four to six inches (10 to 15  CM)  from  the  top  and  have  a  hose  to  direct the water away from the tank and the operator. EXPLANATION OF PICTURED BRINE TANK This    tank    has    three    vee-shaped    electrodes connected and insulated at the center and to the side    frames.        The    large    center    hole    and numerous    small    holes    allow    complete    water circulation  during  the  turbulence  caused  during load application. This unit is very sophisticated and is only shown as   an   example   for   constructing   a   brine   tank. Many  applications  do  not  require  a  load  bank this elaborate. By following the basic construction    guidelines    listed    earlier,    a    less expensive tank can be constructed. For     example,     three     oil     barrels     electrically connected   will   provide   about   a   150   kW   load when   using   round   electrodes   about   3   inches (8cm)  in  diameter  and  18  inches  (45cm)  long. Discarded     pipe     with     random     holes     burned through the surface makes very good electrodes. 127
