Accura 2300/2350-3PSC[1PSC, 1PSCSH] Split-core Power Measuring Module
Split-core power measuring module is a core separation structure, so it can be installed in live state without
power interruption. The following is an example of installing the split-core power measuring module used in
the distribution board[or switchboard]
Fig 1.5 Split-core Power Measuring Module InstallationExample
1. Split-core single-phase single-hole power measuring modules can be used in three-phases by installing one module per
phase [A, B, C] and grouping them. In the case of three-phase three-wire connection, it is possible to measure three-phases
only by installing two modules on phase A and phase C.
2. Packaged with device. Core conductor of 6C telephone line should be minimum 0.128mm
2
[26 AWG]. It is recommended
that distance from power line is 5mm or more so that interference caused by noisy power line will not occur.
3. Ethernet communication is for dedicated communication with upper program.
Note
Accura 2350-1PSCSH Split-core single-phase single-hole power measuring module is recommended in the
following cases.
-
Through-hole current exceeds 250A
-
Difficult to make through-hole wiring because of a large gap between busbars[or cables]
