The Impact of Cable Length on the Protection Level of Surge Protective Device The subject of SPD installation is rarely mentioned in our discussions. There are two reason: The installation of surge protective device should be conducted by an qualified electrician. We don't want to mislead that this should be done by users. And if [...]
SPD Application in High Altitude Areas As an international player in surge protection filed, Prosurge has a very extensive clientele around the world. For example, we have many customers in the South America where is very famous for its plateau. Sometimes, we have customers asked us: We need to install the surge protection device in [...]
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 [...]
