PM1000 Series Power Meters PLSED309039EN

Chapter 5 – Installation 08/2010

Setup — System Type

The power meter needs to know the type of system to which it is connected

to. This information is programmed in the setup procedure, before using the

power meter. The power meter does allow you to change this setting while it

is running; however, this capability is meant for correcting a gross error, or

for training or educational purposes; it is not to be changed on regular basis.

The options are:

 Wye/Star: For 3-phase 4-wire, three Watt-meter or three Element

circuits. Here, all three voltage phase signals, the neutral voltage

connection, and all three current input signals need to be wired in. This

means all the four voltage terminals, and six current terminals described in

the following section, need to be wired. For wye/star wiring configuration,

see ―3-phase 4-wire WYE connection with 3 CTs and 3 PTs‖ on page 43

for more information.

 Delta: For 3-phase 3-wire, two Watt-meter or two Element circuits. For

delta and open delta wiring configuration, see ―3-phase 3-wire Delta

connection with 2 CTs and 3 PTs‖ and ―3-Phase 3-Wire Open Delta

connection with 2 CTs and 2 PTs‖ on page 44 for more information.

 2-phase: For 2-phase 3-wire, two Watt-meter or two Element circuits.

Here, the two voltage phase signals, the neutral voltage connection, and

two current input signals need to be wired in. This means that the three

voltage terminals and four current terminals described in the following

section, need to be wired. For two phase wiring configuration, see ―2-phase

3-wire connection with 2 CTs‖ on page 45 for more information.

 Single-phase: For single-phase 2-wire, one Watt-meter or one Element

circuits. Here a single voltage Phase signal, the neutral voltage

connection, and a single current input signal need to be wired in. This

means that two voltage terminals and one current terminal described in the

following section need to be wired. For Single phase wiring configuration,

see ―Single phase connection with 1 CT‖ on page 45 for more information.
