It can be used to for example, to measure the difference between
neutral and earth.
2.3.2.2 Currents
Permanently installed 1 A or 5 A CT’s, or clamp-on CT’s interface directly to the
galvanically isolated current inputs.
The instrument calculates the “missing current” by assuming the sum of all currents
is zero. (Please refer to Section 2.4.4 for more info)
Alternatively, 1 V
RMS
voltage output current transducers can be used to measure
current.
Current to voltage transducers can interface directly to 4 low voltage differential
inputs. (Please refer to Section 2.4.5 for more info)
2.3.3 Power sources
The instrument is powered from a power factor corrected AC supply input (90–300 V
AC/DC).
It can also be powered from an IEEE 802.3-2008 compliant PoE Plus (< 12 W) source.
The internal LiFePO
4
battery powers the instrument in the absence of power. This
battery guarantees 2,000 charge/discharge cycles. If cycled once per day, it translates
to at least a 5-year useful life.
Please refer to Section 2.4.2 for more detail.
2.3.4 Communication
Two (2) Gigabyte Ethernet ports facilitate local and networked external
communication. One port is used to interface with corporate networks (DHCP or
fixed IP support). The second Ethernet port is used to create a local network by
means of being a local DHCP server. Please refer to Section 0 for more detail.
The remote support software supports automatic service discovery protocols.
Laptops, when connected to the Impedo DUO, will receive an IP from the instrument.
The remote support software can automatically discover which instruments are
connected to the local network.
