Power Supplies
Description
This session will introduce the main criteria for selecting variable frequency drives and their required maintenance for sustainable operation.
Mechanical loads characteristics
Safe operation and initialization
Required routine maintenance
Drive interface with process controllers
IEC and NEMA standards
This seminar topic will discuss the impact of VFDs when installed in an industrial environment as related to the power system and to the electric motor.
Topics such as Harmonics, Line transients, power surges and other power quality issues will be discussed providing the student an insight of how these everyday electric power disturbances will create undesirable effects if not mitigated.
Power Harmonics
Transients
Surges
Long motor feeder cables
Bearing currents
Electro Magnetic Compatibility, noise issues
Inverters today have an extremely fast switching time and this step change in voltage can cause communication issues, high motor stress and even damaging current flow through motor bearings. The student will learn how and why the VFD can create these problems and see the effect of damage that can occur if left unchecked.
