Design Specifications
"The purpose of this project is to develop a three-phase four-wire AC power monitoring system capable of data logging voltage phase-phase, voltage phase-ground, current, and power. The system will alert a user at the occurrence of any transient event, as well as permit the user the ability to change the sampling rate, and possess enough memory to log data for 1 week with a sampling rate of 100 milliseconds."
The product design specifications, according to the sponsor:
1. System must run off 120 VAC wall outlet
2. Ability to measure voltages up to 600 VAC
a. Voltage clamps must be used to clamp onto system being monitored
i. Quick disconnects into the system must be used.
b. Voltage resolution: +-1%
3. Ability to measure current up to 100 Amps
a. Current loops must be used to loop around system being monitored
i. Quick disconnects into the system must be used.
b. Current resolution: +-1%
4. Memory to log data for 1 week with a sampling rate of 100 milliseconds
5. User interface for control of system, data viewing
a. Control of;
i. Sampling rate
ii. Time clock
iii. Voltage transient reference
iv. Voltage +- % for transient
v. Clear all data function
vi. Copy data to external memory device
vii. Enter location of system (zip code)
b. Monitor;
i. Current voltage, amperage, and power
1. Line voltage, phase voltage, line current, true power.
ii. Voltage, amperage, and power versus time graph
iii. Transient events that occur, along with time stamp of when occurrence took place
1. Voltage swell, dip or outage
2. Elapsed time event occurred
6. USB memory stick port for removal of data
7. Internet capabilities to alert user via email if any transient event occurs
a. Voltage swell, dip or outage
b. Elapsed time event occurred
