1 TVSS (Transient Voltage Surge Suppressors) What is a Transient Voltage Surge? Transient Voltage Surge TVS is responsible for a substantial percentage of your capital equipment expense, bombarding your equipment with unneeded electricity. This excess electricity creates heat buildup, causing heat stress and wear on microprocessors and sensitive electronics. Heat escalation caused by TVS also causes moving parts in motors to expand, and breaks down essential lubricants. Expansion causes friction between parts, creating drag and decreasing efficiency. Equipment responds by working harder and drawing more electricity, in turn building up more heat, creating a damaging cycle. Your motor centric systems unnecessarily increase your power consumption, and all electrical devices are more likely candidates for repair or replacement than those protected by Bottom Line Focus, Inc. s TVSS (Transient Voltage Surge Suppression) system. STATISTICS ON POWER PROBLEMS Under voltage, Over voltage, outages and others Voltages Spikes 40% Transient Voltage and Noise 48.5% IEEE Report Impact of Utility Distribution Systems on Power Line Disturbance 1976 GW-Allen and Seagall. According to prominent IEEE report, 88.5% of all external and internal power disturbances are transients, spikes and noise.

2 Where does they come from? Transent Voltage Surge comes from two sources: 1. External - Lightning strikes, Power grid modulation. 2. Internal - Switching of Inductive loads - like Motors, Generators, Air Conditioners, Photo Copiers, PF Capacitors or any other heavy duty Office Equipment. TRANSIENTS SURGE NOISE SURGE Transients are (typically a few nano, micro or milliseconds duration) SURGE - LARGE AMPLITUDE VOLTAGE / CURRENT PROBLEM > 2x nominal Vp EFFECT - HARDWARE DAMAGE SOLUTION- TVSS WITH FILTERING ( LIFE INSURANCE) NOISE - EFFECT - SMALL AMPLITUDE FAST RISE VOLTAGE PROBLEM < 2 x nominal Vp SOFTWARE / HARDWARE ERRORS, SYSTEM LOCK-UP SOLUTION- FILTERING SYSTEMS OF CAPACITORS ARE GOOD CAPACITORS & INDUCTORS ARE BETTER (HEALTH INSURANCE)

3 How Surge voltage travel? TVS travels via: The coupling of surge voltage from one system to another can be Inductive, Capacitive or Galvanic. Inductive Coupling This occurs with magnetic field of a current carrying conductor. This magnetic field induces the voltage peaks in nearby current loop. Capacitive Coupling Possible discharge from one conductor to another conductor where there are large potential difference. Galvanic coupling Here surges voltages couple directly from the interference source to susceptible equipment using common impedances. What does a Transient Voltage Surge (TVS) Cause? TVS causes: 1. Unneeded electricity bombarding your equipment. 2. Excess electricity creates heat buildup, causing heat stress and wear on sensitive electronics. 3. Heat escalation causes moving parts in motors to expand, and breaks down essential lubricants. 4. Expansion causes friction between parts, creating drag and decreasing efficiency. 5. Equipment responds by working harder, drawing more electricity, in turn building up more heat. 6. Unnecessarily increase your power consumption. 7. All electrical devices are more likely candidates for repair or replacement.

4 What is the Solution? Install Liebert Transient Voltage Surge Suppressors The TVSS system stops erratic transient voltage surge and their costly effects with best of breed low-voltage clamping devices installed on your main electrical panel and subpanels. Your business will be fully protected from damaging catastrophic external strikes, and also from the constant barrage of smaller voltage spikes caused by your own equipment internally. Your equipment will operate cooler and will not work as hard, thus reducing the amount of power required to operate. This benefits you by shrinking your power bill and stretching the life of your equipment.

5 How does TVSS Works? TVSS-Transient Voltage Surge Suppressors 1. Operate instantaneously to divert a surge current to ground. 2. Safe guard all types of electrical & electronic devices from high voltage transients caused due to lighting and large-magnitude surges. Good Surge Suppression and Filtering to Work Properly
