Part 1—Surge Protective Device Specification Guide for Low Voltage Power Distribution Systems
This specification guide is Part 1 of a series of such guides that is intended to provide guidance on the evaluation, specification and/or use of surge protective devices (SPDs) deployed in low voltage power distribution system applications. This specification guide describes a uniform specification methodology for SPDs, containing at least one non-linear component, that are […]
Susceptibility of Electrical and Electronic Components to Surge Damage
The NEMA Low Voltage Surge Protection Devices, 05VS, has been asked to provide an overview of electrical and electronic equipment surge susceptibility. This overview will help the electrical community, engineers, consumers, and technicians understand the various transient conditions to which electrical and electronic equipment may be subjected. The intent is not to evaluate individual companies’ […]
Lightning Protection: Preventing a Direct Strike
In the first quarter of 2017 alone, thunderstorms caused a record $5.7 billion in losses, and lightning kills and average of 30 people a year. Learn how to keep you, your family, and property safe from lightning. Lightning is Deadly An average of 22,600 fires were caused by lightning between 2007 and 2011 According to Aon Benfield’s […]
Surge Protection – More than an Accessory
Summary In 2017, the Electrical Safety Foundation International (ESFI) conducted a survey of electrical designers, planners, and engineers and found that there was a limited understanding of the purpose and effectiveness of surge protection devices. In response to the survey results, ESFI created educational materials to spread awareness of surge protection. An important factor revealed […]
Surge Protection – Keeping your Electronics and Home Safe
The National Electrical Manufacturers Association estimates that 60-80% of surges originate from internal sources (within a home or business). Keep your valuable electronics safe by protecting them from the surges that can damage or destroy them. What is a power surge? A power surge is a sudden and unwanted increase in voltage that can damage, degrade, […]
Surge and Protect
National Electrical Safety Month 2015 What is a “Power Surge”? A power surge, or transient voltage, is a sudden and unwanted increase in voltage that can damage, degrade or destroy the sensitive electronic equipment in your home or business. Causes: The National Electrical Manufacturers Association (NEMA) estimates that 60-80% of surges are created within a […]
