What is a network analyzer and how it works
A network analyzer is a device designed for true rms measurement (TRMS) of electrical quantities of single-phase or three-phase systems, with or without neutral, with balanced and unbalanced load. The measurable quantities are: voltages (chained and phase), currents, active, reactive and apparent power, active and reactive energy, frequency, power factor (cosφ), phase angle. Current inputs are isolated and must be made by current transformer; secondaries can be grounded. It has two relay outputs that can be configured as minimum or maximum outputs on any quantity or as pulse outputs for energy counting. System quantities can be displayed.
Display
On the front of the device are:
- the backlit display for displaying electrical quantities
- four buttons for device management
