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
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 instantly indicate output voltage
• Facilitates testing
Load-independent
output
• To display true symmetrical sine and
square waveforms
• 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 testing
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
overvoltages
• 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
Return voltage
indication
• To monitor external high voltage
greater than 100 V (AC)
• Improves safety
