HOW COMMON ARE TRANSIENT VOLTAGES?
Contrary to what we're often told by customers ("We don't have a transient problem"), the presence of transients is well known and well-documented. Consider the following:• A study by IBM indicates that transient voltages account for more than 88% of all recorded power quality events.
SEE ARTICLE• A study by General Electric proved the presence of numerous transient voltages in excess of 2,000 in a small manufacturing facility.
SEE ARTICLE
• The United States Navy recently determined that pay-back from installation of surge suppression equipment averaged a year or less.
SEE ARTICLE• A leading computer magazine indicates that transient activity is the cause of 80% of computer related problems.
SEE ARTICLE• Many government facilities require installation of surge arrester/surge suppressor equipment.

• Major insurance companies note the need and benefit provided by surge suppression equipment installations. Insurance reductions or offsets for such installations may be available.

WHAT ARE THE EFFECT OF TRANSIENT VOLTAGES?
Transient voltages effect different devices different ways. Relatively small transient voltages can cause the immediate failure of electronic devices, but even other equipment can be susceptible. SEE ARTICLEEquipment-specific effects can range from incremental damage of insulation and windings in motors, relays, and solenoids, to immediate failure from destruction of electronic components. Computers, CNC controllers, programmable logic controllers, and motor drives can suffer shut-downs and resets due to logic corruptions caused by the sudden change in voltage.

How quickly and how much damage is done is related to two factors...how much equipment is in the facility that produces transient activity, and how active this equipment is.
| The chart below demonstrates how energy is used in many commercial facilities. Inductive loads are the largest producers of transient voltage within the facility. To illustrate how much of a facility's load can be attributed to inductive (motor & transformer loads), we have colored inductive loads on the chart as shades of blue. |

The amount of transient activity within any facility is related not only to the numbers and types of loads, but how often they are turned on-and-off. The chart below lists broad categories. |
