TVSS/SPD Application Highlights for Waste Water Treatment
|
|
Primary Hot Spots:
PUMPS - Motors located outside of buildings, sometimes several hundred feet away, often run aerators, bar screens, mixing devices and other equipment. These motors have severe lightning exposure and need to be protected accordingly.
SUPERVISORY CONTROL & DATA ACQUISITION (SCADA) - Modern treatment facilities have some of the most sophisticated and critical computer systems made. These systems are subject to internally generated surges as well as external surge activity, and the equipment is extremely susceptible and delicate in nature. The results of data loss can be as costly, or more so than even equipment failure.
MOTOR CONTROL CENTER - MCCs provide power to drives, motors and electrical panels. Loads at the MCCs may be the strongest producers of internally generated surges in the facility.
LABORATORIES - All water and waste water treatment plants have sophisticated laboratories that use sensitive equipment to test the quality of the material being processed at various stages of their processing.
SECURITY/VIDEO MONITORING SYSTEMS - These are extremely critical and always subject to surge related issues. Larger facilities rely on these systems to monitor many different applications. In addition, large municipal facilities can have multiple layers of security (cameras, electronic barricades, gates, touchpads...) each with the possibility of needing SPDs.
BUILDING WIRING - It is a little known fact that a major amount of damage to building wiring is associated with surge activity. Surges tend to reduce the quality of wiring connections within the building, which eventually leads to electrical failure. This is why a system-wide surge protection system is essential.
RESERVE POWER - Back up power systems, such as generators, require protection at the automatic transfer switches (ATS). The electronic controls in the ATS are vulnerable to surges. If the ATS fails to transfer power, the results can be serious. Also; especially on start-up, generator power may not be an acceptable grade for use on electronic equipment and other sensitive loads.
EXTERNAL LIGHTING - External lighting systems are prone to high energy transients due to environmental exposure.
NOTE: Due to the sensitive nature of some equipment, most of these applications will require the use of Sine Wave Tracking SPDs. However, care should be taken to use non N-G tracking products (Option N) to prevent interruption of commonly used GFI systems, where present.
REAL SOLUTIONS:
Testimonial by James Caldwell,
Lift Station Supervisor, Charlotte-Mecklenburg Utilities
As of February, 28, 2002, we have installed SSI units in four of our largest lift stations in Mecklenburg County. To date, all of our equipment has been working properly. One of SPDs was sacrificed last year when we received a power spike at out Long Creek Lift Station. Fortunately, none of our equipment sustained any damage. We were never able to determine if the spike was from lightning or caused by a utility system worker re-energizing our lines. But, after already experiencing an electrical fire at this station several months before, it was very comforting to see how well the SSI units performed. We continue to consider other applications for surge suppression, and will certainly call on Surge Suppression Incorporated to assist us with those needs.

| Product Selection by Electrical Panel Size for Low Voltage Systems:
Product Selection is composed of three primary factors:
Load Size: If the application is a service entrance or the first protected panel in the system from the source of power, then use an SPD with a Peak Surge Current (PSC) of 180-240 Amps per phase for any system 1,600 Amps or less. Use an SPD with PSC of 300 Amps per phase for applications between 1,600 and 2,000 Amps. Consult factory engineers above 2,000 Amps.
Sub-Mains/Distribution Panels/MCCs (non-service entrance): Use an SPD with a PSC of 180 Amps per phase for any Sub-Main/Panel/MCC 1,600 Amps or less. Use an SPD with a PSC of 240 Amps per phase for any Sub-Main/Panel/MCC over 1,600 Amps.
Branch Panels: Use an SPD with a PSC of 120 Amps per phase.
Environment: Take the prior example for instance, if the environment is one where there have been reports of significant level of equipment loss or other suppressors have failed in the past, it may be best to increase the PSC per Phase by as much as 50%.
Connected Equipment Sensitivity: If the load were made up of highly sensitive equipment such as computers or other equipment utilizing microprocessor or integrated circuit controls, the Sine Wave Tracking (Frequency Responsive) Technology is recommended. If the equipment is more rigid, such as motors or lighting, then utilize the Voltage Responsive Technology. |

| About Us |
|
Surge Suppression Incorporated and our affiliated companies are manufacturers and suppliers of multiple lines of quality Transient Voltage Surge Suppression (TVSS) devices for AC and DC power, data, and telecommunications with voltages from .5V to 7200V. We started business in 1982 as an independent distributor of TVSS devices. Over the years, we have provided both quality TVSS devices and quality service to our customers. Due to the original TVSS manufacturer's sale to a foreign corporation, we decided to found Surge Suppression Incorporated. Starting with a core group of experienced and dedicated TVSS industry professionals, our stated purpose was the manufacture of TVSS devices which would not only exceed the standards of the products we sold before, but set a new standard for quality, performance and design ingenuity. Hard work, dedication and the continuing addition of experienced TVSS professionals and resources have all contributed to our rapid growth and industry leadership position.
Surge Suppression Incorporated has extensive application experience across a full range of industrial, commercial and Department of Defense sectors. We value each customer and are committed to providing only the highest level of service and product quality. This commitment can be seen in the success we have achieved with the most demanding and discriminating of customers. After extensive research and testing, an affiliated company was awarded a 2.8 million dollar contract with the U.S. Navy in 2001 to provide TVSS devices for shipboard applications. We have also provided TVSS devices for a number of U.S. Navy, U.S. Marines, U.S. Army and U.S. Air Force installations throughout the United States and overseas. We are very proud to be an active participant in these vital efforts.
Surge Suppression Incorporated has grown and expanded throughout the U.S. and international markets. We currently have sales offices located across the U.S. and in various locations in Europe, Asia, Central America, South America and the Middle East. During this period of rapid growth, we have maintained our commitment to customer service, technical support and responsiveness. |
