Power Mains ON – OFF operation is done by means of an ON – OFF switch along with ‘ON’
lamp indication& Fuse protection.
‘HT’ ON – OFF push along with ‘HT ON’ lamp indication.
Continuously variable autotransformer of suitable capacity to increase the output test voltage
up to the required voltage level.
Zero start interlocking will be provided to ensure that the HV circuit cannot be energized
unless the regulator is initially kept or brought back to zero position.
Automatic tripping mechanism for protecting the DC HV Set against over loading. After
tripping, High Voltage will be switched OFF.
If the voltage is raised beyond the maximum rated value a lamp & buzzer will indicate over
voltage for DC output.
Output DC High Voltage is measured by means of properly designed Potential Divider and
analog readout unit with proper scaling factor. The HV arm of potential divider is an
integrated part of DC high voltage assembly.
