1 ABB Arc Flash Protection Portfolio - Features and Applications Karl Smith M.S.E.E, P.E Product Application Specialist
2 Overview Introduction to ABB arc flash products highlighting new features and innovations Safety culture at ABB followed by a brief tutorial on arc flash protection Product offering and descriptions Application examples of REA arc flash protection system Standard pre-configurations and order code generated drawings for Relion with arc flash option
3 ABB Arc Flash Protection Solutions Relion family of IEDs
4 REA - Features and Innovations Protection at the speed of light Optical arc flash technology and solid state tripping elements using Insulated Gate Bipolar Transistors (IGBT) react instantly (<2.5 ms) to isolate the arc. Advantages are minimal arc exposure to personnel, equipment damage Patented Sensor fiber can detect light through its entire length making the entire fiber a sensor. The fiber can be as long 60 metres. Benefits are reduced insulation costs Continuous self-supervision of sensor fiber loops, operating voltages and cabling between main modules and extension modules makes arc flash protection system more reliable Selectivity The use of extension units allows the protected area to be expanded and the protected object to be divided into smaller areas Easy of use All arc flash modules are settable using switches on the relay front panel. Although the modules communicate with each other you do not need software to communicate with them
5 Application for Fast Arc Quenching
6 Speed and Performance Demo
7 Proven Track Record Over 3,500 REA systems utilizing long fiber-optic sensor technology have been installed in 36 countries around the world City of Richland Alaska Tanker CO LLC Nucor Steel Monsanto Springs
8 Relion - Features and Innovations Built in arc flash function available with optional communication modules. All trip logic is pre-programmed into standard default configurations. The IED contains 3 light detection channels which can be used for detecting arcing faults of the circuit breaker, bus bar and cable compartment of metal enclosed switchgear (uses lens sensors). High speed output contacts (typical operating time is 1ms) available with optional binary I/O modules. Recommended for arc flash. Advanced relay technology The IEDs utilize the most advanced technology and are highly flexible. Particularly, the native IEC protocol which is, now more than ever, very easy to configure.
9 Comparing the Technologies * Results obtained during KEMA testing
10 Incident Energy and Clearing Time
11 Evaluating Arc Flash Options Relion - REF615 for Main and 4 Feeders with arc flash option and high speed outputs REA 10_ (Option A) - REA 101 for main and 4 REA 103 extension units for feeders REA 10_ (Option B) - REA 101 for main and 4 REA 105 extension units for feeders (selective tripping)
12 The Trade-Off for Speed Option Relion REF615 (with arc flash option and high speed outputs lens sensors w/ 5m fiber) Main - HAFCCCC1FFE1BNN1XE (1) Feeder - HAFCCCC1FFE1BAN1XE (4) Relay Operate time (REA/Relion ) 6 ms (Measurement mode needs to be set to Peak-to-Peak ) Price Increase (%) est. (From Relion base line*) 50% A - REA 101 (1), REA 103 (4) < 2.5 ms 64% B REA 101(1), REA 105 (4) < 2.5 ms 66% * Relion base line is no added features with exception of reclosing for feeders
13 Arc Flash Protection is about Safety Arc flash poses a significant threat to individuals who are exposed to live electrical equipment (typically 480 V and higher) Severe burns, injury and even death can result
14 Safety Culture at ABB Integral part of value pairs that define ABB s behavior and commitment to its customers, employees, and stakeholders Lived every day through our actions and philosophy Don t look the other way
15 ABB Value Pairs Safety and Integrity Customer focus and Quality Innovation and Speed Ownership and Performance Collaboration and Trust
16 Danger of Arc Flash to Personnel
17 Arcing Incidences Happen
18 What is an Arc Flash? The result of a rapid release of energy due to an arcing fault between phases, neutral or a ground. Air is the conductor Can be caused by an object to close to a conductor or insulation breakdown
19 How severe is it? Heat - Hot gases, melt drops and thermal radiation may cause damage even farther away (4 times temperature of the sun) Pressure - A rapid temperature rise may lead to a violent explosion (Copper expands 67,000 times) Poison - Toxic chemical compounds may be formed at high temperatures
20 When Does It Occur?
21 Industry Standards IEEE Standard Guide for Performing Arc Flash Hazard Calculation NFPA 70E-2015 Standard for Electrical Safety Requirements for Employee Workplaces OSHA 29 Code of Federal Regulations (CFR) Part 1910 Subpart S NFPA National Electrical Code (NEC)
22 Mitigation Strategies
23 Time is a Critical Factor
24 Time Overcurrent Relays are Slow
25 Effects of Faster Clearing Times Less incident energy developed by arcing fault current. May decrease arc flash boundary (approach distance when worker is exposed to 1.2 Cal/cm 2 ) May reduce Hazard Risk Category (0 4). Determines requirements for protective clothing and Personal Protective Equipment (PPE)
