FREE ECRE Technical Skills Evaluation Questions and Answers
A wind turbine generates an output voltage of 400V at a frequency of 60 Hz. If the voltage needs to be transmitted over a long distance, what device is required to step up the voltage?
Correct!
Wrong!
A transformer steps up or steps down voltage levels for efficient power transmission, reducing losses during long-distance distribution.
In an electrical circuit, what tool is used to measure current flow?
Correct!
Wrong!
An ammeter is specifically designed to measure the current flowing through a circuit, typically in amperes.
What is the primary purpose of Maximum Power Point Tracking (MPPT) in a solar energy system?
Correct!
Wrong!
MPPT ensures that the solar panels operate at their optimal power output, improving the efficiency of energy conversion.
Which software is most commonly used for designing and simulating renewable energy systems?
Correct!
Wrong!
MATLAB/Simulink is widely used in renewable energy projects for simulating and optimizing system performance, including solar and wind energy setups
In a battery management system (BMS), what is the purpose of a thermal sensor?
Correct!
Wrong!
Thermal sensors are essential for detecting temperature changes in a battery, protecting it from damage due to overheating or thermal runaway.
