Several devices are available to monitor the quality of the line power. These devices provide a continuous record of line performance by analyzing and printing out data for the three most common voltage disturbances. Monitor the power line 24 hours a day for seven consecutive days. If inspection of the printout indicates disturbances, stop the test and take corrective action. Monitor the power again as previously described.
A power line disturbance analyzer detects and records most types of line power problems. The Dranetz™ system is an example of a suitable analyzer. In some countries, you can rent power line analyzers from electrical equipment suppliers.
