N/A

The need for AC power lightning and surge arresters is on utilization voltage lines (600Vrms and below), single and three phase, feeding electrical and electronic equipment vulnerable to overvoltage and surge current transients. Installations are made in appropriate locations between the secondary of the power transformer and the equipment to be protected.

Lightning trouble may occur due to direct hits or by induction from nearby strikes. Surge troubles are associated with man-made "switching" transients in operation of electrical equipment. Lightning may be the only problem, switching surges may be the only problem, or both may be the problem. The lightning and surge arrester is insurance of protection against damage. Unlike the accident insurance policy, the arrester pays off before the lightning/surge accident can cause trouble.

The choice of Light, Medium, Heavy, or Extra Heavy Duty surge arrester is dictated not by size of the facility, since lightning and surges are not selective, but by:

• The risk willing to be taken
• The cost of the downtime of equipment
• The cost of repair of equipment
• The importance of "staying on the air" even if the cost of the equipment is minimal
• The estimated severity of lightning strikes and occurrence of surges

The choice of using a surge arrester at all is often made after the first "accident". If not, after the second or third occurrence one is convinced that lightning can strike twice!

N/A AC POWER LIGHTNING AND SURGE PROTECTIVE DEVICES (SPD)
FOR SINGLE & THREE PHASE, TO 1000 VRMS, 50/60 Hz SERVICE

1. For use at : service entrance, transfer switch, distribution panels, and directly on the equipment itself requiring protection; at service entrance for line side or load side of the main disconnect means.
2. Instantaneous and automatic in operation, no re-setting required. Conduction of overvoltage condition starts immediately and extinguishes the instant the transient passes. Response is less than one nanosecond. Protection provided in all applicable modes, L – L, L – N, L – G, N – G.
3. Gapless – no spark gaps. High energy, multiple, solid state devices are used for dependable protection of sensitive equipment. There is no impulse breakdown voltage.
4. KVA unlimited. The SPD is connected across the power lines on any KVA rated source or load. Series impedance (inductors, resistors, etc.) not used.
5. No power follow current : The SPD conducts transients and stops conduction the instant the line voltage returns to normal.
6. Bipolar operation. Clamping voltages are of same value in either polarity of the transient.
7. The SPD provides protection against transients coming in on the power lines or generated from within the facility.
8. Routine testing not required. Periodical maintenance not required. The SPD has no moving parts and draws no power current. The condition of the SPD is continuously self-monitoring with indicator lamps and optional remote alarm relays installed in each phase : These show whether or not the TVSS is operational.
9. Life of the SPD generally exceeds the life of the equipment being protected.
10. Surge Current (8/20 µs wave) ratings per mode to 240,000 amperes. Special designs for ultra critical applications are rated equivalent to 1,200,000 amperes per mode.
11. Indicator lamps and remote alarm relays (provided with NO and NC contacts).
12. Temperature range -55° to +170° F; altitude to 20,000 ft.
13. SPD is completely enclosed in appropriate enclosure for any specified environment: outdoor, indoor, water hose down, corrosive atmosphere, explosive atmosphere.
14. Detailed specifications are provided for each specific model.
15. Lightning Protection Corporation designs and manufactures under strict quality control measures of ISO 9001-2000, registration certified by Underwriters Laboratories, File No. A5103.
