Our comprehensive range of Multifunction Energy Power Meters are expertly designed for accurate and reliable measurement across both single-phase and three-phase energy systems. Capable of measuring active energy, power factor, and AC current, these meters provide a versatile solution for energy management. They facilitate direct connections or can be utilized with a current transformer, accommodating a wide array of communication protocols, including Pulse, Modbus, Ethernet, and Profibus. For ease of installation, we offer models suitable for both DIN rail and panel mounting.
Additionally, our Power Quality Analysers are essential tools for diagnosing a range of power quality issues. They excel in identifying problems such as voltage dips, transients, and surges, alongside both extended and momentary interruptions. These analysers are particularly adept at uncovering issues related to harmonic waveform distortion and frequency variation. They offer comprehensive insights into power factor anomalies and active energy fluctuations, thereby ensuring the integrity and efficiency of your electrical systems.
A power network meter is an instrument that measures electrical parameters such as voltage, current, active and reactive power, power factor and energy consumption across single-phase or three-phase supplies. Power network meters are typically panel or DIN rail mounted and provide a continuous, real-time view of how much energy a system is using, making them essential for energy management, cost allocation and equipment monitoring.
A power quality analyser goes beyond basic energy measurement to diagnose problems within the electrical supply itself. It detects and records issues such as voltage dips, surges, transients, harmonic distortion, frequency variation and both momentary and extended interruptions. Where a power meter answers "how much energy is being used", a power quality analyser answers "is the supply itself behaving as it should", which makes it a key tool for identifying the root cause of nuisance trips, equipment faults or inconsistent process performance.
A power meter is primarily concerned with measurement: tracking active energy, power factor and current for billing, monitoring and efficiency purposes. A power quality analyser is primarily concerned with diagnosis: identifying disturbances and anomalies in the supply that could be damaging equipment or causing downtime. Many modern instruments combine both functions in a single unit, but if your priority is simply tracking energy usage, a power meter is usually sufficient, whereas if you're troubleshooting unexplained faults, flickering equipment or repeated trips, a power quality analyser will give you the diagnostic detail needed to find the cause.
Depending on the model, a power network meter can measure and display active energy, reactive energy, power factor, voltage and current across each phase, along with total harmonic distortion (THD) for both current and voltage. This data can be read locally from the front panel or communicated to a PLC, SCADA or building management system via protocols such as Modbus, Ethernet or Profibus, allowing continuous remote monitoring of energy use and system health.
