The parameter limits are as follows:
Vmax
(690 V input option) = 828V @ PT Ratio = 1
Vmax
(690 V input option) = 144 × PT Ratio [V] @ PT Ratio > 1
Vmax
(120 V input option) =144 × PT Ratio [V]
Imax
(50% over-range) = 1.5 × CT primary current [A]
Pmax
= (Imax × Vmax × 3)/1000 [kW] if wiring mode is 4LN3 or 3LN3
Pmax
= (Imax × Vmax × 2)/1000 [kW] if wiring mode is 4LL3, 3OP2, 3DIR2, 3OP3 or 3LL3
d
Positive readings of kvarh net
e Negative readings of kvarh net
f
To get block interval demand readings, specify the number of demand periods equal to 1
(see Table 5-2)
g
When the 4LN3 or 3LN3 wiring mode is selected, the voltages will be line-to-neutral; for any
other wiring mode, they will be line-to-line voltages.
(P) available in the PM130P and PM130E
(E) available in the PM130E
NOTE
Writing a zero to one of registers 280-286 causes reset of all maximum demands.
Writing a zero to one of registers 287-294 and 301-302 causes reset of all accumulated
energies.
