6 Some things are beyond our control

7 Some things aren’t Our investment in electronics such as computers, energy saving lighting systems, security, building automation, and video is dependent on the power quality without and within our facilities We can’t control the forces of nature but we can protect our business critical sensitive electronics

8 2003 Black Out – North Eastern USA The power outage of August 14, 2003 in the eastern part of N. America left 50 million people in the dark. 61,800 MW of load was disrupted for up to 4 days. When the power came back people lost electronic equipment.

9 Transient Voltage Surge Suppression Overview

10 What is Transient Voltage ? Voltage spikes are high energy short duration transient voltage events that damage or destroy sensitive electronic equipment. Measured in milliseconds they occur in a fraction of a cycle. Equipment Affected All equipment with printed circuit boards and microprocessors are susceptible to transient surge damage.

11 Characteristics: High level surges, 10kA – over 200kA Immediate Catastrophic Damage Examples: Lightning Strikes Utility load switching Fault Clearing Crossed Power Lines Damaged transformers 20% of Transients come from External Sources

12 These high energy transient voltage surges (spikes) last less than a fraction of a second but cause catastrophic immediate damage to electronic equipment and circuit boards Transient Voltage Surges are the culprits that are destroying this sensitive electronic equipment Fuses and breakers simply cannot react fast enough to stop a transient voltage spike

13 Lightning Strike Density Isochronic map USA Lightning causes between $250 - $500 million each year in property damage across the US. * Based on analysis of insurance claims vs cloud –to-ground lightning flash data by the National Lightning Detection Network More than half of these losses are related to electronics

14 Computers Electronic Ballasts Cash Registers ATMs Building Automation HVAC Systems Manufacturing Equipment Medical Equipment Drives PLCs Electronically Controlled Motors Security Systems Audio & Video Equipment Telephones Sensitive Electronics

15 AM – PM It’s a matter of time Your Choice Pro-Actively protect your equipment now or spend more money and time repairing, replacing, procuring, & shipping. Add to that down time, safety issues, lost production, compromised quality, compliance, penalties, and availability to name a few.

16 Are you cruising full speed ahead without considering the cost ? What’s the real cost of equipment failure ? Labor Per Hour $30 High Bay Equipment $200 Procurement Cost $100 Transaction Cost $100 Disposal Cost $50 Downtime Cost $1000 + Example: Ballast Cost $30

17 Characteristics: Low level Repeated multiple events Cause damage over time Examples: Compressors Inductive loads –(i.e) motors & pumps HVAC Units Elevators Drives – control elevators Laser copiers Cleaning equipment –Vacuums, Floor polishers 80% of Transients come from Internal Sources

18 The cost of protecting sensitive electronics from damaging transient surges is only a fraction of connected equipment investment Facility Power Quality Review Qualify & Quantify TVSS Needs Six Easy Steps to Take 1.Evaluate Protection measures currently in place 2.Estimate $ value of electronic equipment 3.Fill out Surge Exposure Cost Worksheet 4.Review electrical distribution layout 5.Count number of electrical panels - note voltage 6.Select appropriate TVSS rating based on location

19 Financial Impact of Surge Damage

25 Nothing?

26 TVSS Technology

27 1 – 100kA High Energy MOV per Mode GE TVSS Design – High Energy MOV L G G L-G= 100kA Phase A

28 Multiple small electronic grade MOV’s mounted in arrays connected in parallel. Typical TVSS Design – Small MOV Arrays G L-G= 100kA Phase A The Requirement for Exact Matching of MOV’s can present potential problems. Since MOV’s are non-linear, matching at lower energy levels does not mean the same performance at higher levels 100kA Rated Array (10kA per MOV)

29 40-50kA Total Energy Transient Tighter Clamping MOV’s cannot withstand energy level. Reduced Rating Potential Problems caused by non-matched arrays G L-G= < 90kA Phase A Other Poorly Matched MOV’s are weakened, reducing the theoretical rating. Typical TVSS Design – Small MOV Arrays

30 Previously Weakened/Degraded MOV’s are now destroyed. Further Reduced Rating L-G= < 70kA Tighter Clamping MOV’s cannot withstand energy level. Subsequent Surges can cause further damage…even with less energy G Phase A Other Poorly Matched MOV’s are weakened, reducing the theoretical rating even lower. Typical TVSS Design – Small MOV Arrays 20-30kA Total Energy Transient

31 GE TVSS Design – High Energy MOV L G Rating is Maintained MOV DOES NOT FAIL! G Phase A L-G= 100kA 40-50kA Total Energy Transient

32 GE TVSS Design vs Typical MOV design GE TVSS Products Incorporate High Energy Metal Oxide Varistor Components 48mm Diameter Dual Wafer Tested to 100kA 20mm Diameter MOV’s Rated 6kA - 10kA Many Manufacturers Use Smaller, Electronic Grade MOV Arrays VS.

33 Maximum Duty Copper Bus Structure Used in High Energy TR7000 Models GE TVSS Design – Components Serial to Surge Path

34 Low Impedance Surge Rated Disconnect Switch Independent test facility verification for 200kA – 8/20us withstand (Optional on Some Models / Recommended when direct bus mounting is required)

35 GE TVSS Design – Components Serial to Surge Path *TPR7000 Series do not require current limiting fuses due to their enhanced thermal disconnect feature. Surge Fusing included on TR5000 and TR7000 models only. *Surge Rated Current Fuses

36 NEW! GE TPR7000 series models are equipped with Enhanced Thermally Protected Metal Oxide Varistor (TPMOV) Technology GE TVSS Design – Enhanced Thermal Protection TPMOV Features Robust 34 mm 2 MOV design. (Equal to 40mm round MOV’s) Thermal Disconnect with proprietary eutectic bond to MOV body. High dielectric strength arc suppression shield.

37 GE TVSS Design – MOV Types Q: When should I specify GE TPR7000 models with TPMOV technology instead of equally rated TR7000 models? A: GE TPR7000 series TVSS models are NEC and UL compliant to be installed directly on the power system bus at any location on the load side of the Main Service Breaker or Fuse. This provides flexibility of installation when a dedicated breaker is not used. Use GE TR5000 or GE TR7000 series if a dedicated circuit breaker is to be applied for outstanding clamping performance Vs.

42 Service Entrance Category C Distribution Category B Point of Use Category A Primary & Secondary Distribution Main … … … Security Computers Video Drives Motors … Internal Transient Sources Xfmr 480V – 120V Internal / External Transient Source External Transient Sources … Layered TVSS Protection per ANSI/IEEE C62.41 Categories of Exposure A/C Branch Panels 120V Sensitive Loads Main Trans former … … … Electronic Ballasts 480V 120V480V TVSS

43 TVSS Application Reasons for Layered System Protection 1) ANSI/IEEE C62.41,45 Emerald Book Guide to TVSS Application Outlines cascading TVSS approach for all categories and exposure levels 2) High level voltage spikes can get past service entrance Voltage spikes from high kA transients can still damage downstream equip 3) Internally generated transients – 80% of all transients Service entrance TVSS cannot provide protection from internal surges 4) Unexpected external transients in distribution – ie Rooftop AC Lightning strikes on building or nearby bring high kA transients into distribution 5) Redundant layered protection at multiple levels Additional layers protect sensitive electronics if upstream devices fail

46 Lighting Ballasts clearly showed sensitivity to everyday transient activity generated inside and outside of commercial and industrial buildings, regardless of manufacturer. GE TVSS eliminated harmful transient surges that can greatly reduce the overall operational life of common products like lighting ballasts resulting in significant cost savings in equipment, reduced downtime and maintenance.
