Energy consumption measurement: The primary function is to measure the total amount of electrical energy used.
Power factor measurement: This indicates how efficiently electrical power is being used.
Overload detection: Alerts the user to potential overload situations.
Data recording and transmission: Many modern meters can store and transmit data for analysis.
System efficiency evaluation: The meter can help assess the overall efficiency of the electrical system.
Three-phase power systems: Designed for use in 3-phase systems where three separate currents are separated by 120 degrees.
