Heat from pig resistance.



 I have found that for my system I require about .3-.5 ohms of resistance
 and about 3mh of inducatnce. These should be placed in series with the
 low voltage side of the pole pig and the power source.  I can vary both
 values to allow for new capaciotr loading in the tank and or replacement
 transformers.

Coilers; I've been reading alot lately about oven/dryer heating elements
being used for resistance in the above manner. But what about the level
of heat dissapated by these things during use? When connected in series
with the 240 volt winding of a pig a 5 KW heating element will probably
generate 2.5 KW, (50%), but that's still alot of heat. How do you
actually install these things; What precautions; Cooling fans?

Thanks, Daniel.
