This is the digital module -Waveform Capture - Disturbance Recording- for Micrologic X trip units in the MasterPact MTZ. A digital module is an advanced feature that can be uploaded to the Micrologic X trip unit at any stage of the product lifecycle. The digital modules allow you to customize the MasterPact MTZ circuit breaker to your specific requirements. The digital modules are available 24/7 from the Schneider Electric GoDigital Store (godigital.schneider-electric.com). Uploading the digital modules is done without power interruption using the EcoStruxure Power Commission software and a USB cable. This digital module automatically records 5 cycles of phase and neutral currents, with a sampling period of 512 microseconds in case of tripping by LSI or G or optional protection devices. Within the 5 cycles of waveform capture, there are 4 cycles before the trip event and 1 cycle after the trip event. The recording can be accessed using the smartphone and the EcoStruxure Power Device in Comtrade format. The recording can be accessed using the smartphone and the EcoStruxure Power Device in Comtrade format. In addition, the waveform capture function records the circuit breaker opening/closing/trip and the ZSI out signal. The advantage is the automatic recording of the waveform, which helps to analyze the tripping event in detail. This allows you to see at a glance the type and severity of the tripping event (with amplitude and duration) and the possible damage to the system.
