Spark spread - Wikipedia

In reality, each gas-fired plant has a different fuel efficiency, but 49.13% is used as a standard in the UK market because it provides an easy conversion between gas and power volumes. The spark spread value is therefore the power price minus the gas cost divided by 0.4913, i.e. Spark Spread = Power Price – (Gas cost/0.4913).Get price

Ultimate Guide to Circuit Breaker Types | Global Electronics

Low-Voltage Circuit BreakersMedium-Voltage Circuit BreakersHigh-Voltage Circuit BreakersMagnetic Circuit BreakersThermal-Magnetic Circuit BreakersMagnetic-Hydraulic Circuit BreakersOther Types of BreakersThese are one of the most common types of circuit breaker on the market and can be found in homes, businesses and industries. They include the following models: 1. Miniature Circuit Breakers (MCB): Miniature Circuit Breakers do not handle currents higher than 100 amps, which makes them suitable for many home and business applications. Once installed, they’re simple to use but not very tunable — you can’t usually adjust their trip settings, for instance. They operate on thermal or thermal-magnetic properties. 2. Molded Case Circuit Breakers (MCCB): These circuit breakers can handle currents up to 2,500 amps, making them a more robust choice for higher-power residential and industrial purposes. With higher amp ratings, their trip load can typically be tuned. What is the difference between MCB and MCCB circuit breakers? MCCBs can handle more voltage, and because of the different requirements set on them, they come in different casing and with different components. Low-voltage circuit b...Get price
