5–12 PQM POWER QUALITY METER – INSTRUCTION MANUAL
A1 METERING CHAPTER 5: MONITORING
THREE PHASE/A/B/C POWER FACTOR: The three phase true power factor as well as the
individual phase A/B/C true power factors is displayed in these messages. The phase A/B/C
true power factor messages will be displayed only for a WYE or 3 WIRE DIRECT connected
system.
THREE PHASE/A/B/C kW MINIMUM: The minimum three phase real power as well as the
minimum individual phase A/B/C real power is displayed in these messages. The time and
date at which these minimum values were measured is also displayed in these messages.
This information is stored in non-volatile memory and will be retained during a loss of
control power. The phase A/B/C minimum real power messages will be displayed only for a
WYE connected system. The setpoint
S1PQMSETUP\CLEARDATA\CLEARMIN/
MAX POWER VALUES
is used to clear these values.
THREE PHASE/A/B/C kvar MINIMUM: The minimum three phase reactive power as well as
the minimum individual phase A/B/C reactive power is displayed in these messages. The
time and date at which these minimum values were measured is also displayed in these
messages. This information is stored in non-volatile memory and will be retained during a
loss of control power. The phase A/B/C minimum reactive power messages will be
displayed only for a WYE connected system. The setpoint
S1PQMSETUP\CLEARDATA\CLEAR MIN/MAX POWER VALUES is used to clear these
values.
THREE PHASE/A/B/C kVA MINIMUM: The minimum three phase apparent power as well as
the minimum individual phase A/B/C apparent power is displayed in these messages. The
time and date at which these minimum values were measured is also displayed in these
messages. This information is stored in non-volatile memory and will be retained during a
loss of control power. The phase A/B/C minimum apparent power messages will be
displayed only for a WYE connected system. The setpoint
S1PQMSETUP\CLEARDATA\CLEAR MIN/MAX POWER VALUES is used to clear these
values.
THREE PHASE/A/B/C PF MINIMUM: The minimum three phase lead or lag power factor as
well as the minimum lead or lag individual phase A/B/C power factor is displayed in these
messages. The time and date at which these minimum values were measured is also
displayed in these messages. This information is stored in non-volatile memory and will be
retained during a loss of control power. The phase A/B/C minimum lead or lag power factor
messages will be displayed only for a WYE connected system. The setpoint
S1 PQM SETUP \ CLEAR DATA \ CLEAR MIN/MAX POWER VALUES is used to clear these
values.
THREE PHASE/A/B/C kW MAXIMUM: The maximum three phase real power as well as the
maximum individual phase A/B/C real power is displayed in these messages. The time and
date at which these maximum values were measured is also displayed in these messages.
This information is stored in non-volatile memory and will be retained during a loss of
control power. The phase A/B/C maximum real power messages will be displayed only for a
WYE connected system. The setpoint
S1PQMSETUP\CLEARDATA\CLEARMIN/
MAX POWER VALUES
is used to clear these values.
THREE PHASE/A/B/C kvar MAXIMUM: The maximum three phase reactive power as well
as the maximum individual phase A/B/C reactive power is displayed in these messages.
The time and date at which these maximum values were measured is also displayed in
these messages. This information is stored in non-volatile memory and will be retained
