The KAD/ADC/008 is a monitor for 3-phase power lines. It measures 40 parameters associated with 3-phase power lines as follows:
- maximum, minimum, amplitude, root-mean-square and average (5x6=30 parameters)
- active, apparent power and their ratio (3 × 3 = 9 parameters)
- period of the VOLTAGE(0) = 1 parameter
The KAD/ADC/008 has a programmable gain amplifier and analog-to-digital converter and a 16,384-point conversion table for each of the six channels. All six channels are sampled simultaneously at 125ksps.
The algorithm waits for a positive-going-zero crossing on channel 0 and resets the maximum/minimum registers for each channel and the accumulators for the various averages. The algorithm ends on a positive-going-zero-crossing after at least 50ms. The processing algorithm is a hard-wired state machine with no micro-code or forbidden states.
Features

- Accuracy (0.3% FSR typical) for 10V range
- 16-bit simultaneous sampling on each channel
- Measures voltage, current, RMS active power, and RMS apparent power
Applications
- Three-phase power monitoring
