Meatrol Mi550 – Three phase energy logger, Energy Analyzer, Electrical Network Analyzer, Power Quality Analyzer, Energy Meter
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.
