Chapter 42, Problem 1RQ
What are the three main electrical test instruments used in troubleshooting?
Expert Solution & Answer
To determine
Three main electrical test instruments used in trouble shooting.
Explanation of Solution
An industrial electrician's main job is to troubleshoot or restore a control circuit when it fails. First, it is necessary to determine which component is at fault in order to repair or remove a faulty component. Three main instruments used to troubleshoot a circuit are the voltmeter, ohmmeter, and ammeter. They can measure several different electrical quantities, so this meters are called multimeters.
Thus Voltmeter, Ohmmeter, Ammeter are the main electrical test instruments used in trouble shooting.

Problem: You and your team are tasked with designing an around-coil system for an air-conditioning unit that will be installed in a hospital. The system must provide a controlled environment for the hospital's air-conditioning needs, ensuring that fresh air is brought in while exhaust air is expelled, without allowing contamination between the two airflow directions.
The air-conditioning system will include two coils and two pumps (one duty pump and one standby pump) in a configuration that accommodates both exhaust and supply airflows. The system needs to comply with ASHRAE Standards, and ASME BPVC Section VIII, with attention to safety, reliability, and efficiency. The system will be used in a climate with moderate temperature variations, and its design will need to consider a range of operating and design specifications.
