The Fluke 1735 for power and energy logging

With the increased focus on the effective use of energy and reduction of waste, more and more industrial and commercial users are analyzing their electrical loading to optimize performance and reduce energy bills.

Electrical load studies are extremely useful to industrial and commercial energy consumers for safety, operational and financial reasons.

These studies include determining and verifying cable and system capacity, balancing load distribution over three phases, keeping track of power factor, and quantifying energy consumption before and after improvements to justify energy saving devices. Understanding power load studies is important for industrial maintenance technicians and external contractors involved in power distribution systems and equipment installation.

In addition, with today’s shifting business requirements buildings are frequently reconfigured to meet needs and demands of the occupiersrom the changing of a production process in an industrial facility to reconfiguration of office space. When a facility requires the addition of new electrical loads to an existing service or set of feeders, the first thing that must be determined is whether the existing system will support the new loads. This is of course essential information prior to additional plant being installed and also important to have a comprehensive understanding of the existing loading in order to evaluate the new system, once installed.

The portable Fluke 1735 Power Logger is an excellent tool for performing load studies for optimizing usage. It includes flexible current probes for connecting around multiple conductors or bus bars, and it has a PC interface and software for downloading and interpreting measurements. The 1735 measures voltage and current on all three phases plus neutral, and records multiple parameters that can help determine system load, including voltage, current, frequency, real power (kW), apparent power (kVA), reactive power (kVAR), power factor, and energy (kWh). The 1735 also includes a number of power quality measurement functions for more detailed analysis of electrical problems.

Fluke also offers the 435 Power Quality Analyzer, a three-phase power quality analyzer which is fully Class-A compliant, has advanced logging functions, user-configurable measurements and a large memory for detailed long-term recording of events Ideal for in depth troubleshooting of power systems..

Of course Power and energy surveys should only be undertaken by qualified personnel and all safety aspects observed.
