Power Quality is a measure of how well a system supports reliable operation of its loads. A power disturbance or event can involve voltage, current, or frequency. Power disturbances can originate in consumer power systems, consumer loads, or the utility.

Why Should I Monitor Power?With the proliferation of computers and other sensitive devices in our professional and personal lives, awareness and addressing of power quality issues is becoming increasingly important. Poor quality of power causes not only physical damage to equipment but also results in downtime (which, in turn, lowers productivity) and a substantial increase in energy costs. Hence, power monitoring is critical to extracting optimal performance out of your devices.
Power monitoring is an important process in identifying current and potential power quality issues and addressing them before they get out of hand. Good power monitoring equipment can provide reliable information about power quality, demand and flow.
What is a Power Disturbance?Power disturbances are defined in terms of magnitude and duration. Disturbances range from transients that last for microseconds to outages that continue for hours. When a power disturbance falls outside operating limits, equipment may be disrupted or damaged.
Lost production: Each time production is interrupted, your business loses profit on product that is not manufactured and sold.
Damaged product: Interruptions can damage a partially complete product, causing the material to be re-run or scrapped.
Energy cost: Electric utilities may charge penalties on poor power factor or high peak demands.
Power Monitoring EquipmentBasic power monitoring equipment consists of the following components:
- Internet or intranet
- A power meter that measures Watts, Amps, power factor, AC power, etc.
- Data storage facilities
