hot-neutral lines or on the neutral-ground lines. Sags are only measured on the hot-neutral lines.

Outage Events Outage events less than one second duration are recorded with half cycle resolution. Longer outages are recorded with 8 second resolution.

Sags and outages are events that are closely related as far as a VER is concerned. If the sag voltage falls below the minimum operating voltage for longer than one second, the event will be recorded as an outage. The VER will go into a low power mode in order to conserve battery life under these conditions.

During the low power mode operation, the VER will only check for adequate line voltage every eight seconds. When the line voltage is restored, normal logging operation is resumed. This mode switching can present confusing event data, especially when sags and outages occur in a sequence.

The following table shows some examples for a 120V VER. The minimum operating voltage for a 120V VER is 70Vrms and the settings are as follows:

Hot to Neutral Thresholds

 

Swell Voltage (Vrms):

128

Sag Voltage (Vrms):

105

Transient Deviation (V):

200

Neutral to Ground Thresholds

 

Swell Voltage (Vrms):

10

Transient Deviation (Vrms):

100

Frequency Thresholds

 

Maximum (Hz):

61.2

Minimum (Hz):

58.8

Examples 1 to 6 represent events that are recorded due to line voltage sags of varying voltages and duration. Examples 7 to 12 show events that are recorded when sags and outages occur in sequence.
