Volts that the line is charged up to = 60kV

Resistor Ohmic value = 250kOhm

Capacitance of line to earth = 5.4microF

therefore total energy stored = 0.5
time constant = C*R = 1.35 seconds

now what i need to know is what power rating does the resistor need to be if it's temperature isn't to go over let's say 50 degrees C based on a duty cycle of 1 discharge every 2 minutes.

I'd appreciate ideas to solve it....I've got some ideas but if anyones done exactly this type of thing I'd appreciate ur input.

many thx
