TEAL Generated Reports

Power Quality Reports

A power monitor connected to your AC power source can be a powerful tool. Unfortunately, they can be complex devices that are difficult to set up, difficult to use, and difficult to extract useful data from. These issues were one of the reasons that TEAL developed the TEALwatch® Power Monitor. Our primary goals were to create a cost-effective monitor that was easy to use and easy to access data.

Many users of the TEALwatch® will find that the summary information provided on the Status page (as shown below) is adequate to understand the power related issues. However, many users may wish to analyze and understand all the details of the power quality. Existing power quality analyzers may offer a reporting tool. However, these automated analysis tools are often limited in terms of diagnostic value, data presentation flexibility, and depth of analysis, or may require expertise to analyze the data.

power quality events (in the green section).

For those that wish to delve further into the power quality data provided by the TEALwatch®, data files can be downloaded (as generic .DAT files) and then opened and charted in a spreadsheet program to re-create the AC waveform that was captured by the monitor during a power quality event. The types of events that can be captured by the TEALwatch® include:

• Event Date & Time - Time stamp of event, based on the internal Real Time Clock (see Advanced tab for more information on how to set the Real Time Clock)

• Event Trigger - Types of Trigger events include:

• Voltage Sag event – Trigger occurs when the AC voltage RMS value drops to a lower than expected value
• Voltage Swell event (also known as Voltage Surge) – Trigger occurs when the AC voltage RMS value rises to a higher than expected value
• Phase Balance event – Trigger occurs when the nominal balance between the 3 AC phases becomes unbalanced
• Frequency Deviation event – Trigger occurs when the AC mains frequency deviates significantly from the nominal setting
• Sub-Cycle (Transient) event - Trigger occurs when a transient event occurs that causes an excursion from the nominal AC waveform
• Power Loss event – Trigger occurs when the TEALwatch® loses power. This helps the user diagnose real system power outage issues and to differentiate when the user has simply turned OFF the main power

• Duration - The duration of the event in seconds

• Minimum Frequency (Hz) - The minimum AC frequency recorded during the event

• Maximum Frequency (Hz) - The maximum AC frequency recorded during the event

Waveforms that are captured can be downloaded by clicking on the "DOWNLOAD" button to the right of each event, or you can "DOWNLOAD ALL FILES " by clicking on this button at the bottom of the page.
