Meet Regulatory Requirements When an Event Occurs
Rapid Capture & Control meets the regulatory requirements of the New Zealand and Australian generation markets and uses Schneider Electric’s high-end power meters and ION software, to deliver a comprehensive solution.
Rapid Capture & Control provides two functions:
- Rapid Capture - high-speed capture of electrical parameters with a given number of seconds before, and after an event. Events may be triggered from under/over frequency or voltage*.
- Control - sending a digital output trip signal to control devices following an event.
How It Works
Rapid Capture & Control combines high-speed monitoring and recording and presents this in graphical format along with raw data.
Frequency triggers are sampled at high-speed every ½ cycle to initiate an event capture. A voltage sag/swell will also trigger a data capture, in Rapid Capture & Control Advanced.
At the conclusion of the event, the event capture report is sent via email. Multiple events can be stored on the meter in the short-term should email communications be interrupted.

A Rapid Capture & Control Report includes:
- High resolution capture of Power, Voltage and Current against Frequency or Voltage*
- Low resolution capture of Power, Voltage and Current against Frequency or Voltage*
- High and low resolution summary of event capture
High Resolution Capture
6 seconds pre event trigger
65 seconds post event trigger 0.02 second intervals |
Low Resolution Capture
6 minutes pre event trigger
16 minutes post event trigger 4 second intervals |
Two Versions Available
Rapid Capture & Control Standard - includes the standard features listed below.
Rapid Capture & Control Advanced - includes standard features plus the recording of additional parameters, multi-meter aggregation and voltage as a trigger. The advanced version is sold on a subscription basis.

Rapid Capture & Control Features
These features are available in both versions.
|
Parameters Recorded
|
A range of parameters are recorded including Frequency, kW total, kvar total, kVA total, VII ab, VII bc, VII ca, I a, I b and I c. The Advanced version also records V1 THD, V2 THD, V3 THD and V unbal.
|
|
Rate of Change
|
The capture of events can be governed by whether the rate of change exceeds a configurable rate. An example of the typical rate of change is 0.05Hz/sec
|
|
Manual Capture
|
Manual captures can be used to perform studies of generator performance in terms of spinning reserve response or for a load shed capability assessment.
Initiation can be from the front panel of the meter, a user with the ION software, via a digital input from a PLC, or via DNP or Modbus communications from an RTU. Rapid Capture & Control detects this manual capture and will perform in the same way as if it were triggered from an excursion. |
|
Power Quality Recording
|
Power Quality features of the ION meters can be utilised such as waveform recording, IEC-61000-4-30 reporting, and Harmonic analysis. These waveforms can then be viewed with the reporting features of the ION software.
The waveforms can be captured as an output from a Frequency related event, Voltage related event (in the Advanced version) or can be captured as the result from a Power Quality related event. |
|
Alert Emails
|
An alert email can immediately be sent to indicate events. A further email is also sent with the event capture report which charts the data and identifies whether the capture originated from a frequency event or manual capture, or a voltage event (available in the Advanced version).
|
|
No Volt Disable
|
Event capture can be disabled for instances when loss of voltage is detected. This prevents unnecessary events being recorded in instances such as a generator going offline.
|
|
Excursion Zoom
|
The excursion is highlighted on an additional set of charts, with much of the pre and post data removed to allow for greater clarity.
|
|
Support for Continuous Log Data
|
When retrieving data for the low resolution capture and summary, if the data was not able to be found for the meter, and the continuous log is running for this meter, the report will use the continuous log data.
|
Advanced Version Features
|
Multi-meter Aggregation
|
Data can be aggregated from multiple ION meters equipped with Rapid Capture & Control, to provide a total system or station response to the event.
|
|
Voltage Trigger
|
Voltage (Sag/Swell) will generate an event and report, in addition to under/over Frequency.
