5.1.2 Test Operations
Every Test operates according to the programmable parameters of the
above sessions. This paragraph will describe the operations of the system in
respect with the programmable parameters.
During Startup the system initializes the Startup Wait Timer - SWT
and the Startup Stirrer Timer - SST. The system introduces an idle
operation time according the 1
st timer, which is used as a ‘Wait time after
filling period’. During this time the system could turn on the stirrer according
the 2
nd Timer. If the 2 nd Timer is zero the stirrer is disabled.
The Test continues the operation according to the parameters described
in the 1 st Stage. The Voltage Parameter and the Duration are inputs to the
voltage controller, which will control the high voltage output. More
specifically, if the voltage value indicates kV then the voltage controller will
immediately adjust (according to the maximum system’s rate) the output
voltage to the programmed value therefore keeping the voltage stable for
the specified Duration Parameter. If the voltage value indicates kV/sec then
the voltage controller will adjust the output voltage according to the desired
rate for the specified duration. It is noted that the Duration Parameter could
take the value “Breakdown” which means no specified duration.
During both situations, if a breakdown is detected the output voltage is
immediately disconnected (turned-off) and the Test Program proceeds with
the After Breakdown Wait Timer - ABDWT and the After Breakdown
Stirrer Timer - ABDST. During the 1
st of these timers the system will be
idle, concerning the output voltage. Moreover, the stirrer will be enabled for
a duration according to the 2
nd timer.
The Test Program will proceed to the stage indicated by the After
Breakdown Stage – ABDSTG parameter (0-29). There are the following
exceptions:
i. Indication of a stage prior to the current stage leads to program
termination
ii. Indication of a stage next (30) leads to next stage
iii. Indication of a stage end (31) leads to program termination
It is noted that after every breakdown the output voltage will be
initialized, thus the next stage’s start voltage will be zero (0 kV). If a
breakdown isn’t detected, the program proceeds to the next stage bypassing
