Amp Litewire
High Voltage Ammeter Probe
Primary distribution probes for CT ratio testing
Supplies an analog output for waveform analysis
Fiber Optic Isolation cable brings the signal to ground
Compatible with most portable test analyzers
The Amp Litewire is a True RMS high
voltage rated ammeter designed to
measure True RMS curent on the primary
side of a distribution network. The sensor
probe is attached to an insulated hot
stick and positioned onto the medium
or high voltage line. A fiber optic cable
connects the sensor probe to a receiver
unit at ground potential, which delivers
the current waveform measurement as an
analog output to a meter analyzer.
The analog output is a reproduction
of the high voltage current waveform,
accurate to the 50th harmonic, and
available as a 0-2 volt AC signal at ground.
This probe provides utilties the ability
to use one of many sophisticated low
voltage scopes, waveform acquisition
recorders, analyzers, or other analysis
instruments, which are otherwise not
capable of analyzing measurements in
primary distribution and high voltage
environments.
The fiber optic cable is physically
rugged, while providing a high speed
data path required for digital waveform
transmission. This cable is also the high
voltage insulator between the two units,
and is specified to provide 100 kV isolation
per foot.
The sensor probe has no moving parts
and does not require clamping onto the
wire. The molded urethane housing is
water resistant and will withstand high
physical impact.
