HARMONIC FILTER SCREEN
The Harmonic Filter screen (See Figure 44) shows important
aspects of the IEEE519 Harmonic Filter in action. In addi-
tion to current and voltage information the Harmonic Filter
Screen also provides the important measure of current Total
Harmonic Distortion (THD).
All IEEE 519 Harmonic filter parameters are displayed on
this page. This information is useful to obtain the status,
operating conditions and diagnostic information for the
Harmonic Filter.
The following parameters display a real value based on the
displayed units:
•
Total Harmonic Distortion Leg,1,2,3 ( %)
•
Total Demand Distortion Leg 1,2,3 (%)
•
Filter Current Leg 1,2,3 (Amps)
•
Supply Current Leg 1,2,3 (Amps)
•
Voltages L1-N, L2-N, L3-N,
•
L1-L2, L2-L3, L3-L1 (Voltage)
•
Total Supply kVA (kVA)
•
Total Power Factor (%)
•
Baseplate Temperature (°F or °C)
•
DC Bus Voltage (Volts)
•
Manual Speed Switch Status (RPM)
