WAVEFORM STORAGE

There are two ways to set up the circuit monitor for automatic event capture:

•Use an alarm to trigger the waveform capture.

•Use an external trigger such as a relay.

This section provides an overview of the steps you perform in SMS to setup these event captures.

To set up the circuit monitor for automatic event capture, use SMS to perform the following steps:

NOTE: For detailed instructions, refer to the SMS online help.

1.Select the type of event capture (disturbance, adaptive, or 100ms) and set up the number of samples per cycle, pre-event cycles or seconds, and duration.

2.Select an alarm condition.

3.Define the pick up and dropout setpoints of the alarm, if applicable.

4.Select the automatic waveform capture option (Capture Waveform on Event). Check the pickup-to-dropout box if you want it to use it for an adaptive waveform capture.

5.Repeat these steps for the desired alarm conditions.

When the circuit monitor is connected to an external device such as a protective relay, the circuit monitor can capture and provide valuable information on short duration events such as voltage sags. The circuit monitor must be equipped with digital inputs on an IOX Extender, or an IOC-44Digital I/O Card.

To set up the circuit monitor for event capture triggered by an input, use SMS to perform the following steps:

NOTE: For detailed instructions, refer to the SMS online help.

1.Select the type of event capture (disturbance, adaptive, or 100ms) and set up the number of samples per cycle, pre-event cycles or seconds, and duration.

2.Create a digital alarm for the input.

3.Select the alarm.

4.Choose the type of event recording you would like.

The circuit monitor can store multiple captured waveforms in its nonvolatile memory. The number of waveforms that can be stored is based on the amount of memory that has been allocated to waveform capture. However, the maximum number of stored waveforms is eighty of each type. All stored waveform data is retained on power-loss.
