Transient Detection,
Metering and Capture Transient detection functionality, available only in the M8 model,
continuously monitors your choice of voltage or current inputs for the
occurrence of a transient. Transients such as voltage spikes and
momentary dropouts can disrupt equipment connected to the power
source, but can be difficult to detect. Use communication to configure
transient capture parameters and retrieve the data for display and/or
processing. The display module does not support an interface for
transient detection. Transient detection includes the following:
•
Continuously monitors all six voltage or six current channels
•
Identifies transients at least 200 microseconds in duration
•
Triggers a transient oscillogram capture when it detects a
transient
•
Records captures each containing 12 cycles; 6 cycles preceding
and 6 cycles following the transient
•
Stores up to six transient captures of all seven voltage and
current channels in non-volatile memory
•
Calculates RMS voltage and current values for each cycle in each
capture
•
Stores each data point in the capture with 13-bit plus sign
resolution
•
Monitors for transients on your choice of voltage channels or
current channels
•
Automatically or manually adjusts transient detection thresholds
You may configure a detected transient to trigger a setpoint, which
may then trigger an oscillogram capture, providing zoom capability.
All communication options support transient configuration, metering
and capture.
Use RSPower, RSPowerPlus, or RSEnergyMetrix software, or create a
custom application, to configure and read transient data. The
following information provides details of the data table interface for
transient detection.
