Meatrol ME435 – Three phase energy logger, Energy Analyzer, Electrical Network Analyzer, Power Quality Analyzer, Energy meter

SKU: EM MT ME435 Kit

R18,200.00

In stock

Install this meter and log a building’s energy for a period of time for example an hour, a week, or one month to get all the data you need.

This handheld three-phase power quality analyser uses external Rogowski coils and voltage-sensing clamps. The flexible Rogowski coils are very easy to install, unlike large CTs. The coils can easily be opened and closed, so no need to disconnect any wires. The voltage-sensing clamps can easily be clamped on, so no need to switch off power. In other words, the meter can easily be installed without any power interruptions.

 

This three-phase energy logger is ideal for the following:

  • Determining the energy usage/load profile of a building’s energy usage over a period of time.
  • Determining a building’s peak power usage.
  • Testing the quality of supply for example voltage dips and harmonic analysis, and establishing if voltage levels are in the acceptable range for PV Inverters.

The results from the energy logging can be used to:

  • Accurately plan solar PV systems, to determine what amount of panels are needed.
  • Accurately plan backup power systems, to determine the size of the inverter and battery capacity needed.
  • Accurately plan, backup generator size requirements.
  • Identify cost-saving opportunities from energy efficiency measures.
  • Identify cost-saving opportunities from improving a building’s Power Factor
  • Identify cost-saving opportunities from Peak-demand(KVA) requirements (Monitor what is causing high KVA usage and when).
  • Monitor and check for phase imbalances to prevent overloading one phase.

Frequently Asked Questions

Does this meter come with all the necessary leads?

Yes, it comes with 4 voltage sensing leads. 3 Current sensing coils, that can measure up to 600A, and a USB power supply and cable. If you want to measure higher currents, then you have to buy larger Rogowski coils, also available here.

How long do the batteries last?

According to the manual only 7 hours, but in our experience the batteries last up to 48 hours (Rechargeable 2500 mAh Duracell). When logging longer periods of time it is recommended to use a USB power supply and connect it to the USB C power supply port on the meter. Alternatively one could also use a large USB power bank, just make sure it is large enough to last the duration you want to log for. A 10 0000 mAh Power bank will last 3 days in our experience.

The data for Power or Energy are not displaying in the Pivot table, what can be wrong?

  1. Try right-clicking on the pivot table and selecting “Refresh Data”, like this.
  2. On the date drop-down boxes select the date you want to display the data for, like this.

How long can I log on to a 4GB SD card?

The amount of space required for one day’s logging at 1-minute intervals is 1 kB. So, on a 4 GB SD card, one can log for more than 8 years.

At ten-second intervals, it will be, six times more data, that will work out to about 4.5 MB per day. So, one will be able to log for about 1.3 years on a 4GB SD card.

What should the CT Ratio be? How do I change between using CTs or Rogowski Coils?

If you are using CTs then use the ratio specified on the CT, however, if you are using Rogowski coils then there is no ratio to be set. You can set the option to use CTs or the Rogowski coils under “Wire settings” in the menu, then “iCon” (Current Connection). So use “CTCon” for CTs and “RCoilCon” for Rogowski coils.

Why does the meter measure 418V on phase A, instead of 239?

It seems that there might be an error in the wiring configuration. Please confirm if it is set to 3-phase 3-wire. Another reason is if the 3000A coil is used, and the current flow is less than 3A, then it can not be measured.

We are measuring negative reactive energy values, is that normal?

It is possible that your loads can generate negative reactive energy. Read this article on Wikipedia.

I used a different SD card, but now the logger does not log data to the card any more. What could be the reason?

The maximum size that can be used with the meter is 32 GB, please ensure the SD card size is 32 GB or smaller. Also, the SD card must be formatted with the FAT 32 file system. Please format the SD card on your computer with the FAT 32 File system.

Our current meter is showing a reading but no current readings are displayed on the screen or in the log file, why?

The current value may not be displayed if the duration that the current flows, is below 1 second. The current is still measured and taken into account for the energy consumption. So if the current flows for very short periods of time, then it will not be recorded. The overall energy usage will still be recorded accurately

Another reason is if the 3000A coil is used, and the current flow is less than 3A, then it can not be measured.

Why does the meter measure 418V on phase A, instead of 239?

It seems that there might be an error in the wiring configuration. Please confirm if it is set to 3-phase 3-wire.
