Electrical safety is very important to the lives of electrical workers. While electricity plays an important role in our everyday lives, it also has the capability to seriously injure or kill a human being. Here are a few essential terms that you’ll find when dealing with electrical safety:
Arc Blast; An explosion of molten material from electrical equipment as a result of high-amperage arcs
Arc Flash; An electrical spark and bright electrical discharge that occurs through the air when large amounts of electricity is present in a gap between conductors
Bonding; Electrical parts that join together to complete a conductive path
Circuit; A complete path of electrical current
Circuit breaker; An electrical device that automatically cuts off electrical current in a circuit when an overload happens
De-energize: The process of the switching off and depleting stored energy sources to equipment and circuits
Energized; Live electrical equipment with available voltage that can produce a current and thus compromising a person
Ground; A direct electrical pathway to the earth
Ground Fault; An electrical current that is lost from the circuit and is instead directed to the ground
Lock-out; A physical lock applied to electrical equipment and electrical circuits once they’re turned off and de-energized
Qualified Person; A person who has received the required training on electrical hazards and on the operation and the construction of the equipment for the job
Overload; An overflow of electrical current in a circuit
Personal Protective Equipment (PPE) Devices; Worn by workers for face, eye, head, hand, foot, respiratory, arm, leg, body, and fall protection
Resistance; The material’s ability to cease or decrease electrical current
Shocking Current; The electricity that goes through the entire or part of the human body
Tag-out; Tags applied to locked electrical equipment informing workers that equipment and circuits are locked out
High Voltage, Inc. introduces the new “The Best Method of Measuring Concentric Neutral Integrity vital to maintaining system stability, reliability, and safety”
The Ω-CHECK® Tester is a unique and very useful product. It injects an AC current through a live cable neutral and measures the voltage drop to calculate the resistance of the neutral to determine the level of deterioration: how many strands have opened due to corrosion. It is a vital tool for URD systems and to measure the resistance of substation ground cables.

Energy Ottawa offers a state-of-the-art, non-destructive cable measurement system for the dependable assessment of medium voltage distribution cables. We have partnered with National Research Council Canada (NRC), the Government of Canada’s premier research and technology organization, to diagnose the health of XLPE cables without damaging them. This unique, on-site diagnostic service determines the health of XLPE cables while preserving their integrity. Based on the DC Polarization/Depolarization Current Measurement principle, it’s a non-destructive method that applies a maximum of 30% of the cable’s voltage rating. Other diagnostic tests often apply 150% of the cable’s voltage rating, further stressing the cables and accelerating deterioration.
Cable deterioration leads to system failure and poor reliability. Our cable testing allows utilities to easily measure the health of their systems and insure against premature, costly replacements. Proper planning ensures that today’s investments will provide lasting value into the future.
