Urban Stray and Contact Voltage Symposium
July 12-13, 2018 | Denver, CO

Download Brochure


Stray and contact voltage conditions regularly appear on a variety of publicly and privately accessible surfaces, and certain cases are costing the industry millions of dollars in litigation. Still, confusion remains between the underlying causes and fundamental differences between the two. The 2018 Urban Stray and Contact Voltage Symposium will address the variances between the two occurrences, known causes, measurement protocol, and mitigation techniques. At this symposium, you’ll explore ongoing utility voltage detection programs, hear best practices regarding measurement and diagnosis, and discover specific techniques that will enhance repairs crew’s ability to mitigate fault conditions.

Learning Outcomes

  • Identify the underlying differences and fundamental causes of stray and contact voltage
  • Determine voltage levels of concern for humans and animals
  • Explore options and methodologies for voltage testing and detection
  • Discuss utility case studies and best practices related to ongoing voltage testing programs
  • Review the National Electrical Code® 680 in relation to swimming pools and hospital areas
  • Discuss the various measurements performed and equipment required to properly mitigate fault conditions
  • Analyze measurement data to diagnosis and determine a course of action for successful voltage mitigation

Thursday, July 12, 2018

8:00 – 8:30 a.m. :: Registration & Continental Breakfast

8:30 – 8:45 a.m. :: Opening Remarks by Chairperson

8:45 – 9:30 a.m. :: Analyzing the Defining Differences of Stray vs. Contact Voltage

Stray and contact voltage conditions can appear on a variety of publicly and privately accessible surfaces.  There are a number of subtleties captured in the definition of the terms.  A discussion of the history of the terminology, application and key differences will be presented.      

David Kalokitis, Chief Technology Officer, Power Survey Company

Stuart Hanebuth, VP of Business Development, Power Survey Company 

9:30 – 10:15 a.m. :: Understanding Underlying Causes of Stray and Contact Voltage

The underlying causes of stray and contact voltage range from a wide variety of faults and system defects to voltage drops occurring from normal system operation.  While both are responsible for voltage appearing of surfaces that are not normally energized, some will require mitigation, and some will not.  A discussion of the underlying causes of each will inform mitigation decision making.

David Kalokitis, Chief Technology Officer, Power Survey Company

Stuart Hanebuth, VP of Business Development, Power Survey Company 

10:15 – 10:45 a.m. :: Networking Break

10:45 – 11:30 a.m. :: Case Study: Safeguarding the Community 

Look under the hood of Seattle City Light’s contact voltage program. Steve Crume, Joint Use and Street Light Engineering Manager, describes the program and shares lessons learned from 8-years of contact voltage surveys.

Steve Crume, Joint Use and Street Light Engineering Manager,  Seattle City Light 

11:30 – 12:30 p.m. :: Contact Voltage Testing and Detecting Methodologies

Accurate and reliable testing protocols designed to identify contact voltage hazards have been implemented in many cities around the world.  These programs have led to reductions in shocks as well as improvements in reliability and reductions in manhole events.  Items to consider when designing an effective mitigation program will be discussed.       

David Kalokitis, Chief Technology Officer, Power Survey Company

Stuart Hanebuth, VP of Business Development, Power Survey Company 

12:30 – 1:30 p.m. :: Group Luncheon

1:30 – 2:15 p.m. :: Stray Voltage around Pools and the National Electrical Code® 680

Overview of the level of protection the NEC® provides against Stray voltage around Swimming Pools and Spas.  Outlines the history, current situation, and  ongoing/upcoming efforts to increase the level of protection written into the  NEC®.

Reuben Clark, President, Consolidated Manufacturing International

2:15 – 3:00 p.m. :: Case Study:  Perimeter Surfaces Equipotential Bonding of Pools in the Vicinity of a Contact Voltage Source  

This case study discusses one example of a contact voltage source in close proximity to two pools.  It outlines the steps taken in the effort to distinguish the source of the stray voltage that lead to identifying the contact voltage source.  The different consequences of a pool with proper equipotential bonding vs a pool with improper equipotential bonding are compared.

Marty Page, Principal Engineer, Southern Company

3:00 – 3:30 p.m. :: Networking Break

3:30 – 4:15 p.m. :: Establishing an Equipotential Area in a Hospital Zone

NEC Article 517 provides requirements for establishing zero differences of potential for patient care areas, such as operating rooms, general care and critical areas.  The purpose of these equipotential areas is to ensure random voltages and currents do not adversely affect both patients and staff in areas where bodily intrusion (electrical equipment penetrating the skin) occurs.

Mark C. Ode, Lead Engineering Instructor, Underwriters Laboratories Inc.

4:15 – 5:00 p.m. :: Residential Stray Voltage Case Study at San Diego Gas & Electric

Stray voltage that is caused by multiple sources can be difficult troubleshoot and resolve. This case study details San Diego Gas & Electric’s approach to identifying and resolving a multiple-source stray voltage condition impacting several residents. The case study will include a discussion of instrumentation used, troubleshooting techniques, mitigation strategies, and interactions with involved agencies. 

Stacy Williams, Principal Engineer, San Diego Gas & Electric
