Fluke 1730 Three-Phase Electrical Energy Logger Technical Data Energy logging is now within your reach discover where youre wasting energy, optimize your facilitys energy use and reduce your bill. The new Fluke 1730 Three-Phase Electrical Energy logger introduces a new simplicity to discovering sources of electrical energy waste. Discover when and where energy in your facility is being consumed from the service entrance to individual circuits. Profiling energy usage across your facility helps you identify opportunities for energy savings, and provides you with the data you need to act on them. The new Energy Analyze software package allows you to compare multiple data points over time to build a complete picture of energy usage, which is the first step to reduce the cost of your energy bill.

Utilities may have other additional charges, in the US the NEC 220-87 is the recommended such as peak demand, which is the maximum standard). Load studies can also identify situations power demand over a defined period of time, where you may be exceeding the allowable load often 15 or 30 minutes. There may also be power on the circuit or when an agreed peak demand factor charges, which are based on the effects of applies from the utility.

The next ques- tion users typically have is how long an energy survey should last. This of course depends on the facility, but it is recommended that you measure for a period that matches a typical facility activ- ity period. If the facility operates over a five day work week with down time on the weekend, a seven day survey will most likely capture typical conditions. If the facility operates at a constant level for 24 hours a day, 365 days a year, a single day could be reasonably representative as long as you avoid a period where there may be planned maintenance. To capture a full picture of the facilities energy usage it is not necessarily required to have measurements made simultaneously at every consumption point in the facility. To get a compre- hensive picture, spot measurements can be made and then compared on a sliding time timescale. For example, you could compare the service entrance results from a typical Tuesday between 6:00 am and 12:00 pm with those of a larger load in the facility. Typically there will be some cor- relation between these profiles. 2 Fluke Corporation Fluke 1730 Three-Phase Electrical Energy Logger
