The PEL51 power logger and energy meter provides a simple but comprehensive solution for electricians seeking to monitor consumption in the context of energy savings or to improve a building's energy efficiency

Product Description:

The compact PEL51 fits in one hand and is easy to handle. Its magnetized casing allows you to position it in smaller electrical cabinets where space is at a premium. No need to cut off the mains to start using it. In addition, it is self-powered via the phase, making it ideal for long campaigns. The backlit multi-display LCD screen is particularly easy to read and is equipped with one channel for the following single-phase measurements:

• TRMS voltage and current measurement
• Power measurement: W (P, Pf), [JP1] VA and var (N, Q₁ and D)
• Measurement of PF, DPF, CF and THD
• All the data is recorded on an SD card [JP2] 

• The PEL51 offers multiple communication modes for real-time monitoring or for saving measurement results:

  • Wifi communication
  • Integrated web server
  • PEL Transfer^® software for data back-up, real-time display and analysis

Energy efficiency and measurement of the savings

When a building or factory is the focus of a global energy survey, electricity consumption is often less than fuel oil or gas consumption, etc. All companies and electricity users have a main meter at the supplier’s point of delivery (RTE in France), but they only very rarely have submetering and may suffer from the absence of a metering point at any time.
The PEL loggers are placed on these points to perform the measurements. The French RE2020 environmental regulations have tightened the constraints for checking and controlling energy spending. Mandatory audits of large companies impose these checks on them. As a result, a number of major groups have failed in their attempts to achieve ISO 50001 certification, which takes this obligation into account and goes even further in terms of seeking out energy savings.

The recordings made with PEL50 electrical measuring instruments are time/date-stamped. This means it is possible to measure the economic gains achieved simply by comparing the recordings made before and after modifications on an installation. The analysis of the recordings made with the PEL50 before the modifications corresponds to a representative period of use. The various operations for maintenance and improvement of the electrical network and equipment, or other purposes, can then be carried out.
A correctly-positioned PEL50 enables you to quickly locate the most crucial points without wasting time. A monitoring period will allow you to establish whether the solutions proposed are correct and sufficient, but above all to precisely measure the savings achieved.

Power Measurements

• Active power P (W)
• Fundamental active power Pf(W)
• Fundamental reactive power Qf (var)
• Non-active power N (var)
• Distortion power D (var)
• Apparent power S (VA).
• And all the related energy measurements.

Recording

• The aggregated measurements are recorded over periods from 1 min to 1 hour on an SD or SDHC card. The data can be read directly on a PC.
