| 3 | Relay and Coordination
Traditionally, utilities have defined reliability as the ratio of the time power was available in a given period divided by the total time in the period. While this is commendable, it is no longer an accurate indication of the quality of service the utility is delivering to its customers. A one second outage will do nothing to impact system reliability, but could be devastating to a single customer.

| 6 | Distribution Harmonics
Harmonic voltages and currents are not new on the system. They have been around as long as your utility has been providing energy service. However, new types of capacitive loads have amplified the condition to the point where it can be a problem for both customer and utility.

| 7 | Voltage Regulators Overview
Voltage regulators are devices that keep the line voltage to sensitive equipment within certain acceptable limits, usually 80 to 135 volts. Voltage regulators are used mostly for linear loads, and for loads that have voltage-dependent automatic shutoffs, such as some mini and mainframe computers. Many, though not all, power-line conditioners also provide voltage regulation.

| 8 | Battery Backup Systems Overview
Often, the solution to power quality problems involves some form of backup power provision. Parallel services and automatic transfer switches handle this. However, the most common source of backup power comes from some type of battery-based system.

| 9 | Wiring
During the last 20 years, society has become more dependent on microprocessor-based equipment such as personal computers, fax machines, and remote controlled televisions. This type of equipment is very sensitive to the electrical power serving it, and power quality problems may have catastrophic results. Often, the power quality problems found inside facilities are the result of, or made worse by, wiring errors.

| 10 | Generators Overview
On occasion, an interruption will last longer than SPS or UPS backup durations. When uptime is critical, some form of external power generation must be available. This is the function of backup generators.

| 11 | Power Conditioners Overview
A power conditioner provides electrical isolation and reduces electrical noise. A power conditioner will help to reduce the impact of electrical noise on your electronic systems. Noise on the power conductor is called normal mode, while noise between the neutral and ground is called common mode.

| 12 | Filtering Devices Overview
Filters are devices intended to provide frequency dependent impedance. At some frequencies there will be very little impedance; at others a very high impedance. Filters are most commonly used in two types of situations -- low magnitude, high frequency electrical noise (or EMI,) and current harmonic distortion.
