Waveform Capture on Trip Event Digital Module
The Waveform capture on trip event Digital Module provides both short waveform capture and long 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:
oTRIP event: activation of the circuit breaker tripping voltage release (MITOP)
oSDE: fault-trip indication contact
oOPEN: open position of circuit breaker
oZSI-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.
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.
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:
oThe EcoStruxure Power Device app must be installed on a smartphone.
oThe smartphone must be connected to the MicroLogic X control unit through Bluetooth, or USB OTG.
oThe MicroLogic X date and time must be up to date.
The Waveform capture on trip event Digital Module is compatible with:
oMicroLogic 2.0 X, 5.0 X, 6.0 X, and 7.0 X control units for IEC standard
oMicroLogic 3.0 X, 5.0 X, and 6.0 X control units for UL standard
oShort waveform capture is available with MicroLogic X control units with firmware version greater than or equal to 001.000.000.
oLong 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.
The waveform capture is displayed in the following ways:
oOn the EcoStruxure Power Device app through Bluetooth, or USB OTG
oIn 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:
oShort waveform capture: wfctxxxx_MM_DD_YYYY_HH_MM_SS
oLong waveform capture: long_wfctxxxx_MM_DD_YYYY_HH_MM_SS
