HV arc around ceramic and glassware Byspeed 4400
HV arc around ceramic and glassware Byspeed 4400
(OP)
Hi All,
During a standard PM service
our service tech has noticed excessive arc spots
all around ends of glassware and ceramic insulators
there is even black arc spots on the brown painted
steel tray below the ceramics I think that means
HV must be jumping about 2 - 3 inches , the ends
of the ceramics are getting black on the outside.
could this be because of a poorly seated oil filter
in the vaccum pump at some point that has cause oil
carry over the the laser cavity and then cause
excessive tracking The machine has 22000 run hrs
and has always had maintenance and is spotless
The service tech siad he has never seen such bad
arc tracking on the outside of the ceramics
Regards
Steve

RE: HV arc around ceramic and glassware Byspeed 4400
I hope he vacuum checked it. Stray HV likes to burn notches in the o-rings in the ceramics.
Make sure the dehumidifier in the bottom of the resonator is working. These resonators do not like humidity. In addition to arcing, the humidity will seep into the backs of the mirror mounts (especially mirror mounts where the mirror is facing down)and start to corrode things. It gets ugly but it's not like a Trumph were the whole resonator has to be replaced.
