Connection Guidelines - Dranetz HDPQ-DN-MVB Quick Reference Manual

Connection Guidelines

Refer to the appropriate connection diagram on pages 28 to 35 for the
voltage and current probe connections that are required when power
measurements are to be made.

Current
connections
Phasor
diagrams
Interconnect
jumpers
Voltage: Voltage probes are connected to the
individual source or load line and are referenced to
the return (common) line voltage probe connection for
greatest accuracy.
Current: Current probes are connected to each line
and positioned to measure currents with reference to
the voltage probe. Incorrectly positioned current
probes may produce erroneous power measurement.
Current probes are always oriented with the arrow
pointing to the load.
Correct phasor diagrams (for resistive loads) are
shown for each connection.
Phasor displays that show incorrect current probe
connection can be corrected by reconnecting the
probe so that the arrow on the probe handle points
toward the load.
The standard cable set for the HDPQ-DN-MVB
includes four (4) interconnect jumpers bearing P/N
114013-G1. These interconnect jumpers can be used
to connect the same conductor points together and
are rated 600V CAT III. When using the interconnect
jumpers, also use the supplied wire markers to identify
the wiring connections applicable to your installation.
WARNINGS
DO NOT EXCEED 600 Vrms when using Dranetz P/N
114013-G1 interconnect jumpers.
For circuit configurations above 600Vrms each
voltage channel input is to be individually connected
to the HDPQ-DN-MVB instrument with the supplied
1000V CAT III cables and safety clips ONLY.
