The Class 8839 58M Enclosed AC Drives are
designed to operate from industrial power systems
with normal AC line conditions without the need of
additional line impedance from either an isolation
transformer or a line reactor. However, when
abnormal line conditions exist, additional line
impedance may be required. Typically, line reactors
are used to:
• Reduce the input rms current to the AC drive
ratings
• Lower the available fault current on high fault
distribution systems
• Limit the total harmonic voltage distortion from
the AC drive at the point of common coupling to
align with IEEE 519 guidelines
• Prevent AC drive nuisance tripping due to
transient overvoltages from power factor
correction capacitor switching
Line Reactors:
1. The line reactors are manufactured by
MTE, Inc.
2. Harmonic compensated up to 150% of
nominal current ratings
3. 5% nominal reactance
4. Refer to the following publications on the
subject of harmonics and benefits of drive
isolation transformers:
