When Does Poor Power Quality Cause Electronics Failures? - Source: EC&M
This article describes the impact of overvoltage, surges, RFI, and harmonics as well as the impact of voltage sag and how grid voltage values, higher or lower than guaranteed nominal values, have an effect on electronic intelligence processing equipment. Incoming grid power “sees” the equipment's DC power supply, which bears the brunt of any AC grid voltage variation.See Complete Article: See Complete ArticleSurge Protection Specification and Application - Source: EC&M
Knowing industry guidelines can save you money and enhance performance.The vast array of surge protection devices, and the ratings that characterize them, can be confusing. This article explains how to sort through all the choices to determine the design strategy and product choices that will provide the protection you need at a cost you can afford using three common approaches.

This article offers advice on selecting the proper TVSS equipment and devices to handle specific loads and dispels the misinformation about TVSS products that is pervasive and convincing enough to lead many people to select and install TVSS devices incorrectly, resulting in unnecessary damage to equipment and costly downtime and repairs.See Complete Article: See Complete ArticleRise of Residential Surge Protection - Source: EC&M
The typical residential customer doesn't know transients come from inside the home as well as outside. For example, the HVAC system that keeps the customer cool in summer and warm in the winter throws transients into the electrical system every time the AC cycles, the heat pump kicks on, or the electronic ignition lights the furnace. The electronic ignitions of gas ranges, dryers, and water heaters also generate transients.See Complete Article: See Complete ArticleSurge Strips vs. Plug-in Power Conditioners - Source: EC&M
If you've ever wondered how surge protector strips are different from plug-in power conditioners, you're not alone. The enormous difference in price makes surge strips especially attractive to many people. To make matters more confusing, manufacturers of these different devices often don't point out the performance differences, which are significant. If you buy any power protection device (including power strips) without knowing the facts, you may find you've purchased far less protection than you thought. The difference between a plug-in surge protector strip and plug-in power conditioner is more than just price. As you will see, surge strips are capable of providing only rudimentary protection.See Complete Article: See Complete ArticleWhat's the Difference Between Surge Arresters and TVSSs? - Source: EC&M
The term “surge protector” can describe any device that protects against surges, which are excess voltages — either impulses or sustained AC overvoltages. If you work in an area that receives a lot of lightning or where electric utility power is unreliable, installing surge protectors will greatly reduce damage to equipment in both commercial and residential buildings. The NEC allows, but doesn't require you to install AC surge protection.See Complete Article: See Complete ArticleSimple Strategies for Surge Suppression - Source: EC&M
People often incorrectly assume that the term surge current capacity, or withstand, describes an SPD's level of protection. Instead, it's simply a rating of how much energy the SPD can withstand before failure. It largely depends on the size of the SPD — a larger one can withstand more energy. Keep in mind that the number of surges an SPD has to withstand will add up — regardless of whether it's one sizable event or several small ones. Specifying excess capacity may mean longer times between replacements — but it doesn't imply a higher degree of protection.See Complete Article: See Complete ArticleInside PQ - Source: EC&M
The primary function of any surge protection device is to identify, in a fraction of a cycle, an overvoltage on the electrical system and divert it to protect other equipment in the system. Although end-users expect a surge protection device to perform this function many times throughout its life, manufacturers in the electrical industry recognize that these devices may have a limited life, in comparison to the facility's entire electrical system. Based on these elementary principles, consider the following TVSS installation factors that will ensure a better performing and more reliable electrical distribution system.See Complete Article: See Complete ArticleApplying Surge Protection Devices on High-Frequency Data Systems - Source: EC&M
With the rising importance and complexity of data networks in today's competitive business climate, the concern of losing communications is steadily increasing. Companies with critical transactions, such as those found in the financial and industrial sectors, have tremendous downtime costs. As a result, these firms depend more heavily on the reliability of their data networks, which run on higher data rates.See Complete Article: See Complete ArticleFire alarm specialists, inspectors stress importance of surge protection - Source: EC&M
With the increase in popularity of low-voltage technology, electrical systems are more susceptible to transient damage and malfunction, and system designers need to put more thought into surge protection on the AC power line and data/communications lines, which feed into fire alarm systems, according to the National Burglar and Fire Alarm Association (NBFFA) and other industry analysts. Nearly 30% to 40% of all damaging transients enter a system via the AC circuit, but an even greater number come in by way of 48V phone lines.See Complete Article: See Complete ArticleInformation About Surge Protectors - Source: New Mexico State University

The most common approach to surge suppression relies on using a variety of commercial-quality, low-current-rated metal oxide varistors (MOVs) or silicon avalanche diodes (SADs) manufactured in bulk, and positioned in parallel arrays on PCBs. However, many such surge-suppression devices (SPDs) place the equipment they are designed to protect in peril, leaving them ultimately unprotected due to improper circuit design, inadequate surge-current capacity, and inadequate testing evaluations.See Complete Article: See Complete ArticleCertifications and Surge Protection - Source: Electrical Wholesaling
As surge protection manufacturers continue to bring greatly improved and safer products to market, the testing and certification process for these products has become increasingly complicated, time consuming and expensive as a result of ever-evolving codes and standards. These requirements are proving extremely difficult for some manufacturers to meet in the current economic climate. As a result, many manufacturers of surge protective devices (SPDs) are opting to go to market without a UL listing on their products.See Complete Article: See Complete ArticleUSE GDTs For Surge Protection In Broadband Digital Comm - Source: Electronic Design
