Performance Specifications and
Design Assumptions

These harmonic filters are designed to limit rms currents to fall within the

reactor rms current ratings assuming that the associated drive is operated

within its ratings and other harmonic producing loads do not exceed the levels

listed below. In addition, filters are designed to allow the capacitors to operate

within their published voltage and current ratings as follows:

• rms capacitor voltage limit:

125% of nameplate voltage

• peak capacitor voltage limit: 135% of peak nameplate voltage

• rms capacitor current limit:

180% of rated 60 Hz current

For variable torque loads the reactors and capacitors have been selected on the

basis that other harmonic producing loads, up to 50% of the drive rating, may

exist on the user or utility power systems. For constant torque loads it is

assumed that there are no other significant harmonic producing loads.

If power factor correction capacitors are present on the plant or utility power

system, consideration should be given to resonant frequencies and potential

harmonic amplification that could occur.

These harmonic filters are NEMA type 1 construction rated for ambient

temperatures between 0 and 40°C (32 and 104°F). They are available with

110/120 V or 220 V control. Standard units are available to compliment the

following drive power ratings:
