A vehicle that gets 30 MPG will cost you $ 925 less to fuel each year than one that gets 20 MPG (assuming 15,000 miles of driving annually and a fuel cost of $ 3.70). Over a period of 5 years, the 30-MPG vehicle will save you $ 4625. Fuel Cost & Savings Calculator.
Load bank checks the engineâs ability to perform and provide the required horsepower when called upon in an emergency. When a load bank is used, the artificial load it provides brings the engine up to an acceptable operating temperature.
These load banks are typically resistive (neither inductive nor capacitive and with no initial switch-on surge. Current rises immediately to a steady state). Load banks are available for either ac or dc systems. An ac load bank is used to test entire UPS systems, whereas a dc load bank will be used to test batteries. Reactive load banks are also available (typically with a lagging power factor 0.8) but they tend to be larger and heavier in design.
