Equipment such as TVs, amplifiers, and receiver boxes would benefit from having this line of defence.\u003c\/p\u003e\u003cp\u003eSurge Protective Devices (SPD) are used to protect installations from electrical power surges known as “transient overvoltages”.\u003c\/p\u003e\u003cp\u003eThey are also used to protect sensitive electronic equipment connected to the installation, such as computers, televisions. Any equipment with sensitive electronic circuitry can be vulnerable to damage by transient overvoltages.\u003c\/p\u003e\u003cp\u003eThe effects of a surge can result in either instant failure or damage to the equipment only evident over a longer period of time. It is important to remember that protecting the electrical installation alone, and not the other services, could leave another route for transient voltages to enter the installation.\u003c\/p\u003e\u003cp\u003eThere are three different types of Surge Protective Devices:\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eType 1 SPD\u003c\/strong\u003e: installed at the origin, e.g. main distribution board.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eType 2 SPD\u003c\/strong\u003e: installed at sub-level.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eType 3 SPD\u003c\/strong\u003e: installed close to the protected load.

Historically this has not been an issue within domestic installations but more recently, installations are changing with the advent of electric vehicle charging, heat pumps have made transients much more likely to occur within domestic installations.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow do SPDs work?\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe gas discharge tube (GDT) is sealed with ceramic and its interior consists of two or more metal electrodes with gaps filled with the inert gases, argon and neon. As the overvoltage passes through, it arcs between the electrodes, allowing current to flow to ground, thus protecting your devices.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eTechnical Information:\u003c\/strong\u003e\u003c\/p\u003e\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eElectrical Characteristics\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e \u003c\/td\u003e\n\u003ctd\u003e \u003c\/td\u003e\n\u003ctd\u003e \u003c\/td\u003e\n\u003ctd\u003e \u003c\/td\u003e\n\u003ctd\u003e \u003c\/td\u003e\n\u003ctd\u003e \u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Code\u003c\/td\u003e\n\u003ctd\u003ePROSPD55F\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eConnection Type\u003c\/td\u003e\n\u003ctd\u003eF-Type\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInterface Type\u003c\/td\u003e\n\u003ctd\u003eMale to Female\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eGas Discharge Tube Arrester\u003c\/td\u003e\n\u003ctd\u003e90V\/230V\/350V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFrequency Range\u003c\/td\u003e\n\u003ctd\u003eDC - 1GHz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Current\u003c\/td\u003e\n\u003ctd\u003eNone\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMax.
