Basics on Power Quality

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 http://www.fluke.com/fluke/inen/products/Power-Quality.htm

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 Damage to : Circuit Boards, Electrical Insulation http://www.fluke.com/fluke/inen/products/Power-Quality.htm

4. Why Monitor it? • Downtime • Data Loss • Products damages during production • Excess Energy Consumption • Additional expense in maintenance, equipment repairs and equipment replacement http://www.fluke.com/fluke/inen/products/Power-Quality.htm

5. Solving these issues • Can be solved by use of clamp meters for measuring power quality and power that allows troubleshooting first level directly into the equipment • Some tools that can be used are: Single phase power Quality Analysers Three phase power quality Analysers Long term power Quality Recorders http://www.fluke.com/fluke/inen/products/Power-Quality.htm
