Going around installing a surge protection device for every piece of equipment in your house is no small feat. Think for a moment. You would probably come up with your computer and your audio video devices but there are several appliances that are connected to a power outlet, from your washer and dryer to the microwave to the vacuum cleaner, I can go on and on. All these devices are vulnerable in case of a power surge. The answer is a complete whole house surge protection strategy. BESST Engineering, Queensland recommends a 3-stage surge protection for your precious home.
Direct Strike Lightning Protection
Lightning conductors or lightning rods are installed on the top of a house or building. In the event of a strike, the conductor would send the excess energy to the ground. As part of residential lightning protection system, BESST Engineering provides Prevection lightning terminals that are fully capable of mitigating the hazards of a lightning surge.
Surge Protection Level 1
These devices protect against externals power surges such as those caused by lightning or when your local power grid switches loads. They can be installed at the point where power enters your house from the utility supply. BESST gives you Gatekeeper surge diverters for installation at the service entrance of your building, in the main switchboard. There are heavy duty versions available depending on your power supply and requirements. Experienced electrical contractors at BESST Engineering, Brisbane can advise you on choosing the one that is right for your house.
Surge Protection Level 2
The protective devices at level 2 are installed where the main line branches out into various circuits inside your house. The advantage with this level of protection is that they protect your house from internal surges which can be caused by devices that switch power on and off such as a thermostat. Gatekeeper LITE surge diverters and surge Filters from BESST Engineering, Queensland are ideal for protection from transients for your sensitive electronic equipment. The modular design, internal fusing and long service life makes them ideal for Class I and II Cat B & C applications.
Surge Protection Level 3
These protection devices most of you would be familiar with. Examples are power strips that are used at point of use, where a device is plugged into a power outlet. Most people only use these and think they have protected their house but the reality is actually the opposite. As you can see, we have put them at level 3. These devices only work as part of a comprehensive protection plan and not as stand-alone devices.
Hire An Expert
Handling electrical equipment is no child’s play. Only skilled electrical contractors such as Batterham’s Electrical Switchboard Services and Trading, BESST at Queensland should be called upon to install whole house surge protection equipment to ensure peace of mind.
We all own expensive electronic devices these days. Computers, printers, scanners, audio visual devices, modems, routers and LAN, expensive stuff is hooked directly to power all the time. Power surges can not only be external (as in a direct lightning strike) but also internal (when a heavy appliance switches power on and off). In the light of this, surge protection for your electronic devices becomes paramount. BESST Electrical Engineering services in Queensland share a few expert tips to protect your equipment.
LAN SURGE PROTECTORS LAN surge protectors provide protection to the database servers and local area network against power surges. The Gatekeeper GKLAN-UTP range from BESST electrical engineers, Brisbane has been designed to provide high energy surge protection for LAN/UTP applications. Being all mode devices, the protectors have been designed for mounting either in-line or in a network rack system. Surge Protection devices can protect LAN hubs, servers and routers from surges coming from coaxial cables.
POE (POWER OVER ETHERNET) SURGE PROTECTORS GKLAN POE (Power over Ethernet) protectors provide full multimode and multistage protection. The Gatekeeper GKLAN – UTP POE rack mount POE surge protector from BESST electrical engineering services is available in a 24-port configuration for 5, 12, 24 and 48 volt applications. These are specially designed to protect sensitive rack mounted electronics and the Ethernet port from electrical and lightning induced surges. The rack mount POE protectors provide dependable safety from a wide range of surges yet only use a little rack space. Easy to install and use, GKLAN POE surge protector is only truefully tested CAT 6 SPD available today.
WHOLE HOUSE SURGE PROTECTION To ensure 100 per cent protection of your equipment, you must also take care to protect to protect your entire house or building from surge as well. Whole house protection includes:
Operator panels, also known as Human Machine Interfaces (HMI) allow interaction between people (humans) and industrial control systems (machines) such as PLC – programmable logic controllers. They can be in various forms - text panels or graphical displays with touch screens. BESST Engineering at Queensland provides MECT Operator Panel with PLC that can help you monitor process critical information. The panel also enables operators to input instructions to check or change the commands to the machine being operated.
The MECT operating panels available with BESST Engineering are equipped with Modbus RTU over RS485 or CANopen, Modbus TCP, or TCPRTU on Ethernet interface. There is a micro USB port that is used for data logging and software update, or as a device for mass storage. For programs and data, an SD memory card can be installed on the operating panels. The panels come with their own software to configure the system and create PLC and HMI graphics applications without the need to write the code. Panels are available in portrait as well as landscape format.
The operator panel with PLC and touch screen can be used for a wide range of applications. Assembly lines, transportation, water treatment, food processing are only a few examples where operating panels with PLC can be used to automate processes. Operating panels with in-built input/output ports can help to monitor process critical variables and control systems by issuing commands to the system. Panels can link directly with a series of sensors and actuators, number of connections vary according to the model.
Lightning rods are enough to protect my building and my equipment
True and False. Electrical contractors, Batterham’s Electrical Switchboard Services and Trading, BESST Engineering, Queensland say that it is true that lightning rods do protect buildings in case fires are caused by a lightning strike. But they do not provide any protection against voltage surge caused due to massive amounts of energy generated during lightning. The electrical systems installation is generally below the ground. The lightning rod conducts current into the ground. Some of it may flow back into your circuits and damage your equipment. For protecting your equipment and appliances, you need surge diverters. BESST provides Gatekeeper surge diverters provides protection against surge voltages and surge currents caused by lightning.
No lightning, no surge, right?
False. Any power disturbances can create transients or spikes. While lightning does cause massive surges, a voltage surge can also be caused by devices that switch power on and off, like an appliance’s thermostat switch. Your area’s grid switching electrical loads can also cause a surge that is enough to kill your sensitive equipment since most of it is designed to operate only at a specified voltage.
My devices are plugged into a power strip. That is good.
False. Power strips are only a way to increase power points on a single outlet. They may save you from a fight about who gets to charge their phone first but they offer no real protection from a power surge. They are as good as plugging directly into the outlet. Only surge protection devices can protect your appliances and equipment against a voltage surge.
i have a surge protector. I am 100 percent safe now.
Depends. Choosing the right surge protection device and correct installation is paramount. Residential and industrial electrical contractors, BESST at Queensland advise that you get expert help to install a surge diverter or arrester. Length of the cable that connects the surge protection device to the mains is a critical parameter among many others like where the building is located, what is the risk level, what is the earthing mechanism and so on. Only experienced engineers and electrical contractors have the necessary knowhow to judge which surge device is right for you and how it should be installed.
Every time there is a surge, the surge diverter is destroyed and needs to be replaced.
False. Surge arresters discharge the excess energy to the ground each time it happens. And they can do it repeatedly. The life of a SPD (surge protection device) is as good as any other protection device. Gatekeeper surge diverters from electrical contractors, BESST Engineering, Brisbane are suitable for installation at the entrance of a building, in the main switchboard or a distribution board. Multiple surge diverters may be used to provide coordinated protection.
