Waveform Capture on Trip Event Digital Module

Presentation

The Waveform capture on trip event Digital Module provides both short waveform capture and long waveform capture.

Short Waveform Capture

The short waveform capture function records five cycles of phase currents and neutral currents after a trip on all standard protection functions and optional protection functions. The sampling period is 512 μs. The short waveform capture function records four cycles before and one after the trip event.

The short waveform capture function records the digital status of the following:

TRIP event: activation of the circuit breaker tripping voltage release (MITOP)
SDE: fault-trip indication contact
OPEN: open position of circuit breaker
ZSI-out and ZSI-in: ZSI signals

Only one short waveform capture on trip event is available at a time. Generating a new short waveform capture replaces the previous one.

At delivery, no short waveform capture is available. A short waveform capture on trip event is available after the circuit breaker has tripped due to any standard or optional protection function. Trips due to tests that are run with EcoStruxure Power Commission software are not recorded.

The short waveform capture is stored in non-volatile memory without requiring an external 24 Vdc power supply.

The short waveform capture is a COMTRADE (Common Format for Transient Data Exchange) file. Refer to the IEEE C37.111 or IEC 60255-24 standard for more information about the COMTRADE file format.

Long Waveform Capture

The long waveform capture function records 50 cycles of phase currents, neutral currents, and phase-to-neutral voltage after a trip due to any standard protection function or optional protection function. The sampling period is 625 μs. The long waveform capture function records 35 cycles before and 15 cycles after the trip event.

The long waveform capture function records the digital status of the OPERATE event when the associated time delay elapses.

Three long waveform captures on trip events are available at a time. Generating a new long waveform capture replaces the oldest one.

At delivery, no long waveform capture is available. A long waveform capture on trip event is available after the circuit breaker has tripped due to any standard or optional protection function. Trips due to tests that are run with EcoStruxure Power Commission software are not recorded.

The long waveform capture function requires an external 24 Vdc power supply to store the waveform capture in non-volatile memory.

The long waveform capture is a COMTRADE (Common Format for Transient Data Exchange) file. Refer to the IEEE C37.111 or IEC 60255-24 standard for more information about the COMTRADE file format.

Prerequisites

The Waveform capture on trip event Digital Module is an optional Digital Module, which can be purchased and installed on a MicroLogic X control unit.

The prerequisites are:

The EcoStruxure Power Device app must be installed on a smartphone.
The smartphone must be connected to the MicroLogic X control unit through Bluetooth, or USB OTG.
The MicroLogic X date and time must be up to date.

The Waveform capture on trip event Digital Module is compatible with:

MicroLogic 2.0 X, 5.0 X, 6.0 X, and 7.0 X control units for IEC standard
MicroLogic 3.0 X, 5.0 X, and 6.0 X control units for UL standard
Short waveform capture is available with MicroLogic X control units with firmware version greater than or equal to 001.000.000.
Long waveform capture is available with MicroLogic X control units with firmware version greater than or equal to 002.000.000.

Data from the Digital Module is available remotely through IFE/EIFE or IFM communication interfaces, if the IFE/EIFE or IFM firmware version is compatible with the Digital Module. For more information, refer to firmware compatibility of the communication interfaces.

Data Availability

The waveform capture is displayed in the following ways:

On the EcoStruxure Power Device app through Bluetooth, or USB OTG
In EcoStruxure Power Commission software

The waveform capture can be exported as a file in COMTRADE format through the EcoStruxure Power Device app or the EcoStruxure Power Commission software, for use with Schneider Electric Wavewin-SE software.

The file names for waveform captures have the following formats:

Short waveform capture: wfctnnnn_MM_DD_YYYY_HH_MM_SS
Long waveform capture: long_wfctnnnn_MM_DD_YYYY_HH_MM_SS
