Revision as of 16:34, 15 April 2013

Date Time (24h) Guard (V) Sense (V) Field (V) Sense ([math]\mu[/math]A) Field ([math]\mu[/math]A) comments
04/08/13 12:27 536 1100 -750 Tripped (trip is set to 10 [math]\mu[/math]A). Initially settled around 4-5 [math]\mu[/math]A.
04/08/13 12:36 536 950 -750 Tripped
04/08/13 12:40 536 850 -750 Fluctuating from 1.5-3.0 [math]\mu[/math]A on both sense and field.
04/08/13 13:32 536 850 -750 Tripped
04/08/13 13:40 536 800 -750 Set trip threshold to 15 [math]\mu[/math]A. Current tripped within 5 minutes.
04/08/13 13:45 536 750 -750 Sense/field fluctuating around 1.5 [math]\mu[/math]A.
04/08/13 14:40 536 750 -750 2 2 HV found in tripped state, set Imax to 100 [math]\mu[/math]A, and restored HV.
04/09/13 07:34 536 750 -750 0.1 0
04/09/13 07:35 536 800 -750 0.1 0
04/09/13 07:35 536 900 -750 0.2 0.3
04/09/13 07:37 536 1000 -750 1.5 1.6
04/09/13 07:37 536 1050 -750 6.2 6.3
04/09/13 10:12 536 900 -750 5 4 Found HV in tripped state, restored sense to 900 instead of 1050, it first tripped when attempting 900 Volts but staged 50 volts increases brought it back without tripping, I observe 30[math] \mu[/math]A spikes at 900 Volts
04/09/13 11:00 536 890 -750 0.1 0 Found HV in tripped state, set HV to 890 any further and 30 [math]\mu[/math]A current spikes occurr, changed trip time from 0.1 to 1.1 sec
04/09/13 13:11 536 900 -750 0.1 0 current is jumping more
04/09/13 13:11 536 890 -750 0.1 0 found HV in tripped state, went back to 890
04/09/13 17:22 536 890 -750 0.05 0.00
04/09/13 17:30 536 970 -750 1.3 1.2 Changed voltage in steps of 10V at a time. Changed ramp rate to 1V/s on sense. Observed some surge currents after voltage stabilized at around 30 - 40 [math]\mu[/math]A for a few seconds.
04/10/13 07:40 536 970 -750 0.115 0.005 Found fields in tripped state, but not sense or guard. Turned on again, current was relatively low.
04/10/13 07:50 536 1080 -750 1.1 1.0 Went up in voltage in 10V increments at 1V/s ramp, monitoring change in average current at each step after voltage settled. Last increment to 1080 saw some surge currents up to 30 [math]\mu[/math]A, but average current is around 1 [math]\mu[/math]A.
04/10/13 10:40 536 1070 -750 0.2 0.3 Found fields in tripped state. Set sense to lower voltage and reset field voltage.
04/10/13 10:42 536 1070 -750 1.3 1.4 Tried turning voltage on sense up to 1080, current and voltage started fluctuating more than usual. Turned voltage back to 1070. Current is still a little higher than when initially started up again at 10:40, fluctuating from 1 to 4 [math]\mu[/math]A.
04/10/13 11:04 536 1050 -750 1.3 1.4 Found Field & Sense HV in tripped state, set Sense HV to 1050 current becomes non zero after a sense wire Voltage of 1000 VOlts
04/10/13 11:25 536 1050 -750 0.2 0.3 tried to increased to 1060 since current fluctuations were small and below 0.2 [math]\mu[/math]A, both sense & FIled tripped so returned to 1050 sense wire voltage setting
04/10/13 12:30 536 1050 -750 0.2 0.3
04/10/13 13:45 536 1070 -750 0.15 0.25 Current instability was observed when taking voltage up to 1075. Backed off to 1040, current stabilized to less than 0.01 [math]\mu[/math]A. Raised back up to 1070V again, current appears stable for the moment.
04/10/13 15:15 536 1070 -750 0.065 0.115
04/11/13 08:30 536 1120 -750 0.065 0.115 Currently raising voltage only 1-3 volts at a time and monitoring sense current for a few seconds before raising again. If sense current stays above 0.075 for more than a few seconds, run-away current instability will usually start-up again.
04/11/13 10:32 536 1130 -750 0.080 0.170
04/11/13 11:25 536 1130 -750 0.080 0.170 HV tripped at about this time
04/11/13 11:25 536 1120 -750 0.080 0.170

04/15/13 08:40 536 1130 -750 0.000 0.090
