Verifying Voltage and Current Connections, continued

Incorrect

current phasor

diagram

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 PowerVisa is able to display diagrams of the various wiring configurations to

assist users in the selection of circuit type appropriate for their application (see Chapter

5 Start Menu - Circuit Type Selection on page 5-11). The instrument compares the

detected voltages, currents, and phase sequence (if applicable) to the selected circuit

type. The PowerVisa issues a message if the specified circuit type and the actual

voltage/current connections match.

The next pages describe and illustrate the wiring configurations available for set up in

PowerVisa.

WARNING

Interconnect Jumpers bearing part number 114013-G1 supplied with the standard cable

set can be used to bond the same conductor points together. To reduce the risk of fire,

electric shock, or physical injury, it is strongly recommended that connections be made

with all circuits de-energized and current carrying conductors fused. If it is necessary to

make connections on energized circuits, these must be performed by Qualified

Personnel ONLY with Proper Personal Protective Equipment.
