3.2 Basic functions

 Applicable phase wire
PGR1C PVS1C
(Electric power (Electric power
/leakage) /voltage sag)
○
O: With setting X: Without setting
• Set the phase wire to be measured.
• Setting range: Single-phase 2-wire, single-phase 3-wire, 3-phase 3-wire, and 3-phase
4-wire (initial value: 3-phase 3-wire)
*1. CTD8E (CT expansion) can perform the two-system measurement only when it is
connected to PMU2A (power two-system).
If CTD8E is connected to PGR1C that measures the circuits of 3-phase 3-wire, 3-phase
3-wire must be set as the phase and wire system applied to CTD8E.
 Synchronization selection for measuring block
PGR1C PGR1C
(Electric power (Electric power
/leakage) /leakage)
×
O: With setting X: Without setting
• Set the voltage system synchronized with a measuring block.
• Setting range: System 1, system 2 (initial value: system 1)
The measuring blocks are divided into measuring block 1 and measuring block 2, which are
assigned to system 1 and system 2, respectively, to perform power measurements.
For PGR1C (Electric power/leakage) and PGR1C (Electric power/leakage), since their
measuring blocks and voltage systems are fixed, the setting of synchronization selection for
measuring block is not required.
 Dedicated CT type
PGR1C PVS1C
(Electric power (Electric power
/leakage) /voltage sag)
○
O: With setting X: Without setting
• Set the dedicated CTs to be used.
• The dedicated CTs are as follows.

CT Model
Model KM20-CTF-5A
Model KM20-CTF-50A
Model KM20-CTF-100A
Model KM20-CTF-200A
Model KM20-CTF-400A
Model KM20-CTF-600A
• Setting range: 5 A, 50 A, 100 A, 200 A, 400 A, 600 A (initial value: 100 A)
* When connecting CTD8E (CT extension) to "Model KM1-PMU2A-FLK"of KM1 series to
measure two systems, set the type of dedicated CT for each block.
