3.2 Design Features
To assure that the workplace is safe and that operators can fulfil their
responsibilities with ease, the HVA provides the following features.
Feature Purpose/application Advantage
Optimized frequency
Selection/automatic load
measurement
• To test capacitive loads
• No instrument restart necessary
• Facilitates testing
• Limits number of
connections to the DUT
Fully automatic test
sequences
• To test according to IEEE or other
standards
• Facilitates complex testing
• Facilitates test repetition
Real time display
• To indicate instantaneous output
voltage display.
• Facilitates testing
Load independent
output
• To indicate true symmetrical
sinusoidal and square wave
waveforms output
• Facilitates testing
Built-in memory
• To save test sequences
• To save test reports
• Facilitates test repetition
• Facilitates documentation
Arc management
• To provide short-circuit protection
• To allow for fault conditioning
• Limits test interruptions
commonly encountered
when using conventional HV
test instruments that
immediately trip on arc
detection.
Automatic load
measurement
• To limit connections to the DUT • Facilitates testing
Intelligent design
• To avoid moving parts and need
for lubrication
• Reduces maintenance
• Improves instrument
durability and reliability
Instrument Lock-
Key switch
• To prevent unauthorized use • Improves safety
Local and remote
emergency OFF
switches
• To shut down operations in
emergency situation
• Improves safety
Fully integrated
discharge and transient
circuit
• To ground the DUT after testing
• To protect the unit from transient
over voltages
• Improves safety
• Protects instrument
Initial load clearance
test at reduced voltages
• To check automatically for shorts
or grounds, during load
measurement, before test
initiation
• Improves safety
