2. What is Power Quality??
• Power Quality indicates how effective is the quality of supply to
support installation and reliable operation of the electrical
equipments
• Electrical Disturbances may originate from an user’s premises or
the power company
• Voltage, current or frequency can be affected by these electrical
disturbance

3. Hidden Power Quality Problems
• Voltage Dips and swells – Caused by large loads starting up or shutting down
 Damage To: Computers, Electronic Controls and Lamps
• Harmonic Distortion – Alteration in current frequency cycles caused by non
linear loads
Damage To : Motors, Transformers, Fuses
• Voltage Unbalance – Differences in Phase Voltages or current of more than
permissible limits
Damage to : Motors and Transformers
• Flicker – Cyclic Voltage Dips
Damage to : Employee Productivity
• Transients : sharp voltage increases caused by equipment switching on and off
