Whole House Surge Protection / Whole Home Surge Protection Today, the concept of whole house surge protection or whole home surge protection is becoming more and more popular. One of the important reasons is that today there are too many electronic devices that are very expensive yet very vulnerable to power surges. It is [...]
We all know that it is not so easy to choose a proper surge protection device. The parameter of a surge protective device is not like the parameter of a smartphone which is obvious and easy to understand for most people. There are a lot a misunderstandings when selecting a SPD. One of the common [...]
Surge Protection Device Classifications In a previous article, we introduced the one of the classification of surge protection device, that is, by type or class. Type 1/2/3 is the most common SPD classification either in UL standard or IEC standard. You can review this article via this link: https://prosurge.com/surge-protection-device/ And in this article, we are [...]
Surge Protection Device Surge protection device (or abbreviated as SPD) is not a product that known to the public. The public do know that power quality is a big problem in our society in which more and more sensitive electronics or electrical products are been used. They know about UPS which can provide uninterrupted power [...]
Surge Protective Devices (SPD) are used to protect electrical equipment against surges (overvoltages) caused by lightning or switch of heavy duty machines (many people may ignore this). It may take some technical background when selecting a proper surge protective device as there are various technologies and regulations. The IEC 61643 standard defines 3 types of [...]
Not necessarily. A Type 1 SPD offers versatility by being able to be connected to either side of service entrance, however UL does not compare the surge clamping performance of a Type 1 SPD versus that of a Type 2 SPD. UL investigates clamping performance of all SPDs equally, without regard for SPD type. UL [...]
It is impossible to prevent voltage surges from either entering your facility or from occurring inside of your facility. When protecting a facility against transients, the best approach is a networked or cascaded approach. As shown in the graphic below, The Institute of Electrical and Electronics Engineers (IEEE) has developed three categories that every facility [...]
Though we try our best to offer an extensive, thorough product presentation on our website, catalogs and other documents, we believe the best way for model selecting is to consult with us with your requirement and then our professional will recommend a suitable model.
The following examines a few of the key differences between Underwriters Laboratory(UL)’s required test for surge protective devices (SPDs); ANSI/UL 1449 Third Edition and the International Electrotechnical Commission (IEC) required test for SPDs, IEC 61643-1. Short Circuit Current Rating (SCCR): The capacity of current with which the tested SPD can withstand at the terminals where [...]
Choosing the right surge arrester(s) is a key factor to guarantee correct protection of the installation. A poorly designed Lightning & Surge protection system may lead to early ageing of the SPD and potential failure of the protective devices in the installation allowing damage to the primary systems up stream, thus defeating the rationale behind [...]
