A portmanteau of variable resistor, the varistor is the active semiconductor in many surge protection devices that stops power surges. It is a voltage dependent resistor (VDR), meaning it operates in a non-conducive (or standby) mode until a higher than normal flow of electricity passes through it. The higher the voltage entering the varistor the [...]

What’s the first thing someone does when they need more outlets than what the two socket wall option provides? They look for an extension cord. An extension cord or extension lead, power board or power strip, whatever you want to call it, provides extra outlets for that specific need but it doesn’t address the bigger [...]

The simple answer is that a joule measures energy absorption. The higher rating in joules a device measures, the better the device is thought to be. With regards to surge protection, when the Joules rating is high, the surge protector is capable of handling a larger surge in a single event before it needs replacing. [...]

It’s not something everyone knows about, but your home is under attack on a daily basis by an invisible threat. If you have any electronics in your home, and most people do – your LCD or plasma television, any media peripherals like DVD players or Xbox 360s, your computer, even your microwave – they are [...]

Since 1936, the group Consumers Union, (otherwise known as Consumer Reports) has guided consumers to making informed choices when purchasing products where otherwise pertinent information was omitted by marketers for the sake of positive advertising. Without question surge protection falls into this category as there is little regulation attributed to the distribution of information by [...]

Here’s a very good question from our readers, “Do surge protectors work when turned off?” It would seem logical to think that when a surge protector that is plugged into the wall would not function if in the off position and would thus expose your electronic gear to all kinds of surge damage; but this, [...]

Plugging your valuable electronic equipment directly into an electrical outlet is risky business. Surges of power through electrical lines happen. You have absolutely no way of knowing or predicting when your electrical system in your home will receive a jolt of extra power either through a lightning strike or energy spike from your power company. [...]

When it comes to Monster vrs Prime surge protectors, there are several important criteria to examine before making an informed decision. Prime has been in the surge protector market for about 20 years. Even though Monster Cable has been on the market for around 30 years does not necessarily make their products better. Ready outlets [...]

Protecting electrical devices against damage from power surges is a wise decision a surge protector can help with. A single 220 volt surge protector, or surge suppressor, is a device that protects powerful electrical equipment—such as welders, washing machines and kilns—from spikes in electricity caused by storms, electrical company failures and internal electrical power fluctuations. [...]

This is a question we hear all the time: Can you daisy chain surge protectors? This means, can you plug one surge protector into another and still receive the benefits of protection. Let me ask you this question: Why would you want to do that? If you are attempting to use one surge protector as [...]

You can find a surge protector for just about any electronic application you need. They range from very cheap to very expensive and the price is dependent on what you need it for and who makes it. This can make shopping for surge protection very confusing for newcomers to the market. For some, it is [...]

A surge protector is a device that often allows multiple electronic devices to be plugged into it in order to allow more device usage from one power outlet and to stop a power surge from damaging the electronic equipment. They come in a variety of styles and with different levels of protection and features. Due [...]

Why does my Monster surge protector trip constantly? Why does my Monster Surge protector beep? People who are asking themselves this question often turn to the Internet for answers. Regardless of what other sites may say, there are some important things you need to know before buying these warranties for any surge protector you choose [...]

Despite global powers being on the frontier of new technologies in power systems, working both toward energy efficiency and eco-friendly pathways so as not to pollute the environment further, there is still a need for traditional power grids that conduct electricity to every domestic home, that is, until these new technologies are realized and implemented.
