DRPD-CAL | Portable Partial Discharge Calibrator
The DRPD-CAL is the industry's
most compact, rugged and portable
calibration instrument used to
generate Partial Discharge (PD)
signals designed for use in industrial
environments to calibrate systems
and provide the utmost in user
convenience.
This partial discharge signal
generator is extremely useful in
performing system calibrations,
the verification of PD sensing and
monitoring equipment, measuring
circuit integrity and charge according
to IEC-60270.
The DRPD-CAL generates multiple
ranges of pulses which are
conveniently spaced allowing for
instrumentation
synchronization
and / or verification including
timing calibration, time-of-arrival
and differential schemes.
Features & Benefits
• A lightweight, compact industrial enclosed
pulse generator that's easily transported
anywhere to meet PD calibration needs.
• Three output calibration channels with
different injection charges 50Hz or 60Hz sine
wave capable.
• Conveniently spaced pulses, starting at zero
crossing for 9- degrees of the sine wave.
• Dual power input; Universal AC Input Power
Adaptor/Charger or rechargeable NiMH
batteries for use in remote or unpowered
locations.
Applications
• Use as a portable (PD) pulse generator.
• Used for calibration of partial discharge
sensors, monitors and PD instrumentation.
• Useful for measuring circuits in terms of
apparent charge per IEC-60270 or other
applicable PD standards.
