Data Center Power Terminology<\/strong><\/h3>\n\n\n\nAlternating Current (AC) Power Circuits:<\/strong> Alternating Current is a term used to describe electricity that is supplied in the form of a sinusoidal wave. AC defined the industrial age due to the simplicity of voltage transformation using static devices (transformers).<\/p>\n\n\n\n- Direct Current (DC) Power Circuits -Alternating Current, on the other hand, is a time-varying approach to delivering electricity. A DC battery uses a direct current to power an electromagnetic coil that converts chemical energy into electrical energy.<\/li>
- Ampere (Amp) – An electric current measurement unit. One ampere is the same as one volt passing through a resistance of 1 ohm.<\/li>
- Kilowatt Hours (kWh) – one thousand watt-hours (see Wh). A kilowatt-hour (kWh) is a standard energy unit.<\/li>
- Kilovolt Amps (kVA) -voltage x current (amperage) (see VA).<\/li>
- Volt (V) -The potential difference, also known as a unit of electrical potential, is the difference in electric power between two points.<\/li>
- Watt (W) -Watts (symbol: W) are a measurement of mechanical power in the United States, with units equal to watts being the product of potential (volts, see V) and current (amps, see A). If the voltage and current are alternating currents, the relationship between watts, volts, and amps is known as power factor (see PF),<\/li>
- Kilowatt (kW) – a standard unit of electrical energy.<\/li>
- Megawatts (MW) -a measure of power equal to one million watts. They are often used to describe the size of data centers in terms of power capacity.<\/li>
- Single-Phase vs. Three-Phase Power –<\/li><\/ul>\n\n\n\n
Single-phase electric power is the distribution of electric energy through a system. Only one leg or phase from a three-phase source is fed to the load by connecting degrees and neutrals or clicking the load between two phases. At the same time, Three-phase power refers to an electric energy system with at least three conductors that transmit voltage waveforms that are 2\u00f0\/3 radians (120\u00b0, 1\/3 of a cycle) delayed in time. Three-phase electrical energy is generated and sent to load centers, where it may be consumed at the Three Phase or Single Phase.<\/p>\n","protected":false},"excerpt":{"rendered":"
Your PC needs a constant supply of electricity to stay online\u2014but your main supply may be unreliable from time to time. If you live in a prone-to power outage location, you might be asking: can a power outage damage a PC, and what measures can you take to protect yourself from its consequences?
