Power Quality Configuration
Power quality configuration is provided by a number of modules, depending on
your meter type: the Sag/Swell module, the Transient module, and numerous
EN50160 frameworks, some of which include the Mains Signalling Evaluation
modules.
Sag/Swell Module Settings
The Sag/Swell module monitors voltage waveforms for sags and swells (i.e. ITI
(CBEMA) Type 2 and Type 3 disturbances); it then reports each disturbance’s
magnitude and duration. The Sag/Swell module can also detect sub-disturbances
during a Sag/Swell event. Settings are as follows:
1 The primary power system voltage is sometimes different than the PT Primary setup register value (i.e.
when the PT Primary is used to indicate winding ratio rather than primary voltage).
Setup Register Function Default
Pulse Width
This numeric bounded register specifies the width, in seconds, of the pulses sent to the hardware
channel. The Calibration Pulser module maintains a minimum duty cycle of 50% on the output pulse
train.
0.05
Kt
The numeric bounded register defines how much energy the module accumulates before a pulse is
sent to the hardware channel. An industry standard for energy pulsing is 1.8, or one pulse per 1.8
energy-hours.
1.80
Int Mode Specifies the modes of integration that may be selected. 1 Absolute
OutputMode
This register specifies whether the output is a complete pulse (Pulse) or a change of state transition
(KYZ).
Pulse
Port
This register specifies which hardware port the output appears on. Only those hardware channels that
are still available appear when you access this setting.
Not Used
Setup Register Function Default
Swell Lim
This is the magnitude above which a voltage deviation is
considered a swell.
106
Sag Lim
This is the magnitude below which a voltage deviation is considered
a sag.
88
Change Crit
This is the amount a voltage signal must change during a
disturbance to be considered a new sub-disturbance.
10
Nom Volts
This is the nominal power system voltage (used for all Power
Quality functions).
0 1
EvPriority
The priority assigned to Sag/Swell and Transient module events
(0 to 255, 255 is highest).
