   it's not a self-regulated capacitor as I first thought, it's a sulfur   
   hexafluoride (SF 6) circuit breaker and the potential transformer is   
   supllying the auxilliary voltage! I suppose they installled them (there   
   are LOTS of them)so as easily to disconnect a part of the line. before   
   that theu had to open the circuit breaker all the way upstream to the   
   150/20 kV substation, open the disconnect switch, which would disconnect   
   the line downstream, and then reclose the circuit breaker. closing again   
   the disconnect switch would cause no problems. you can see here upstream   
   a disconnect switch.
