The Primary current recorder uses the same
sensor technology as the original Rogowski coil. The True RMS inductive sensor
does not use magnetic materials. The opening of the sensor is electronically
closed and external currents are electronically rejected.
The accuracy, external current reject, and range of currents measured
by the patented amp sensor substantially exceed the performance of the best
clamp-on sensors. The true power factor is calculated by measuring the electric
field in comparison with the current reported from the amp sensor. The key
feature of the unit is the ability to leave it deployed on the line to record
readings every 15 minutes for 90+ days. It easily attaches to the line with a standard
insulating bar. Once on the line, it immediately begins to collect and record
the current and power factor on the line.
The Primary current recorder is equipped with an 433 wireless port for
communicating the recorded data into the user`s PC. The data is downloaded
through GF 2015 PC-Link software, which allows the user to download,
view and query the data stored on the Primary current recorder.
The housing of the Primary current recorder is made of ABS+PC and is
built to operate safely, even in severe utility environments. It is resistant
to shock, repels water and is un suceptible to flame. It also operates within a
wide temperature range. The Primary current recorder has a the screw insulation
bar of installation, which allows it to hang on the line securely in all weather
PC-LinkSoftware is a user-friendly software interface that
allows the user to download, view, graph and export data from the Primary
current recorder into Microsoft Excel. The data directly transfers from the Primary
current recorder into Excel through an 433M Port.
