Model 3640 Power Line Monitor

The model 3640 Power Line Monitor exercises its power to closely examine the causes of a power anomaly because it monitors unpredictable failures (changes) in power lines and records waveforms of the power line failures as well as computes and prints out the maximum and minimum values, distortion factor, frequency, and harmonics.

	Features extensive functions to monitor the quality of power supplies.
	Prints out waveforms and analysis data.
	Prints out data logging reports every hour.
	Analyzes up to the 63rd harmonics.

The data logging features two functions.

1. RMS values of the voltage and current, frequency, distortion factor, active power and power factor of a monitored power supply are calculated every cycle; their average values for one second are determined; the maximum, minimum, and average values of the voltage, current, frequency, distortion factor, and power factor and the integrated value for active power for every hour are recorded based on the above results; and the averaged and integrated results are printed once every day or every hour on the hour.

2. One cycle (from the fundamental to the 63rd) harmonics of a monitored power supply are analyzed and printed out every hour on the hour.
