Standby power, also called vampire power, vampire draw, phantom load, ghost load or leaking electricity phantom load and leaking electricity are defined technical terms with other meanings, adopted for this different purpose, refers to the way electric power is consumed by electronic and electrical appliances while they are switched off but are designed to draw some power or in a standby mode. This only occurs because some devices claimed to be switched off on the electronic interface, but are in a different state from switching off at the plug, or disconnecting from the power point, which can solve the problem of standby power completely. In fact, switching off at the power point is effective enough, there is no need to disconnect all devices from the power point. Some such devices offer remote controls and digital clock features to the user, while other devices, such as power adapters for disconnected electronic devices, consume power without offering any features sometimes called no load power. All of the above examples, such as the remote control, digital clock functions andin the case of adapters, no load powerare switched off just by switching off at the power point. However, for some devices with built in internal battery, such as a phone, the standby functions can be stopped by removing the battery instead. In the past, standby power was largely a non issue for users, electricity providers, manufacturers, and government regulators. ITM of Emergency Power Systems.

In the first decade of the twenty first century, awareness of the issue grew and it became an important consideration for all parties. Up to the middle of the decade, standby power was often several watts or even tens of watts per appliance. By 2. 01. 0, regulations were in place in most developed countries restricting standby power of devices sold to one watt and half that from 2. DefinitioneditStandby power is electrical power used by appliances and equipment while switched off or not performing their primary function, often waiting to be activated by a remote controller. That power is consumed by internal or external power supplies, remote control receivers, text or light displays, circuits energized when the device is plugged in even when switched off, etc. Power can be saved by disconnecting such devices, causing at worst only inconvenience. While this definition is inadequate for technical purposes, there is as yet no formal definition an international standards committee is developing a definition and test procedure. The term is often used more loosely for any device that continuously must use a small amount of power even when not active for example a telephone answering machine must be available at all times to receive calls, switching off to save power is not an option. Timers, powered thermostats, and the like are other examples. An uninterruptible power supply could be considered to be wasting standby power only when the computer it protects is off.

Advantages and disadvantageseditAdvantageseditStandby power is often consumed for a purpose, although in the past there was little effort to minimize power used. It may enable a device to switch on very quickly without delays that might otherwise occur instant on. This was used, for example, with CRT television receivers now largely supplanted by thin solid state screens, where a small current was passed through the tube heater, avoiding a delay of many seconds in starting up. It may be used to power a remote control receiver, so that when infrared or radio frequency signals are sent by a remote control device, the equipment is able to respond, typically by changing from standby to fully on mode. Best Cx Designer Software there. Standby power may be used to power a display, operate a clock, etc., without switching on the equipment to full power. Battery powered equipment connected to mains electricity can be kept fully charged although switched on for example, a mobile telephone can be ready to receive calls without depleting its battery charge. DisadvantageseditThe disadvantages of standby power mainly relate to the energy used. As standby power is reduced, the disadvantages become less. Older devices often used ten watts or more with the adoption of the One Watt Initiative by many countries, standby energy use is much diminished. Devices on standby consume electricity which must be paid for. The total energy consumed may be of the order of 1. The cost of standby energy is easily estimatedeach watt of continuous standby consumes about 9 k. Wh of electricity per year, and the price per k. Wh is shown on electricity bills. Electricity is very often generated by combustion of hydrocarbons oil, coal, gas or other substances, which releases substantial amounts of carbon dioxide, implicated in global warming, and other pollutants such as sulphur dioxide, which produces acid rain. Standby power is a significant contributor to electricity usage. As electricity consumption increases, more power stations are needed, with associated capital and running costs. Standby devices mean that heat is generated, which can mean extra cooling is needed, and in the wrong circumstances can be a fire risk. Standby devices are not always completely silent. Standby means electric power is present in the device, increasing electrical interference, and making the risks associated with electricity a 2. Standby devices can often be remotely controlled, sometimes by unauthorised or irresponsible agents, or by accident. MagnitudeeditStandby power makes up a portion of homes miscellaneous electric load, which also includes small appliances, security systems, and other small power draws. The U. S. Department of Energy said in 2. Many appliances continue to draw a small amount of power when they are switched off. These phantom loads occur in most appliances that use electricity, such as VCRs, televisions, stereos, computers, and kitchen appliances. This can be avoided by unplugging the appliance or using a power strip and using the switch on the power strip to cut all power to the appliance. Standby power used by older devices can be as high as 1. W per device,3 while a modern HDLCD television may use less than 1 W in standby mode. Some appliances use no energy when turned off. Many countries adopting the One Watt Initiative now require new devices to use no more than 1 W starting in 2. W in 2. 01. 3. Although the power needed for functions such as displays, indicators, and remote control functions is relatively small, the large number of such devices and their being continuously plugged in resulted in energy usage before the One Watt regulations of 8 to 2. W,4 and around 31. In Britain in 2. 00. British residential power consumption. A similar study in France in 2. In 2. 00. 4, the California Energy Commission produced a report containing typical standby and operational power consumption for 2. Over a decade ago some electronics, such as microwaves, CRTs and VHS players used more standby power than appliances manufactured in the last 5 years.
