- Expertly diagnose and fix problems on the job.
- Assure quality and safety compliance with time-saving charts, tables and diagrams.
Designed for quick reference at any job site, the Electrician's Troubleshooting and Testing Pocket Guide enables electricians using portable meters to test, maintain, and troubleshoot all types of electrical equipment and systems.
This updated classic now features:
- Expert guidance on all the latest troubleshooting tools, testing instruments, systems, and equipment.
- Time-saving charts, tables, and diagrams for assuring quality and safety compliance.
- Vital material on personal protective equipment (PPE) required for testing energized circuits.
- New material: coverage of new equipment, such as infrared scanners and power quality analyzers; information and guidelines that comply with new NFPA 70E safety requirements.
From the Introduction
Electrical measuring and testing instruments are used in the installation, troubleshooting, and maintenance of electrical systems of all types, particularly in commercial and industrial facilities. Electricians and technicians involved with installing, maintaining, and repairing electrical equipment need a good working knowledge of portable testing instruments and how they are used to diagnose and fix problems in the field.
Most operational problems of electrical equipment and systems involve one of four basic faults:
- Short circuit
- Ground fault
- Open circuit
- Change in electrical value
This guide describes troubleshooting techniques to identify such problems using portable field-testing instruments. Although it covers many types of test equipment, this book emphasizes the use of digital multimeters (DMMs), the most common and versatile electrician's diagnostic tool.
This new third edition of Electrician's Troubleshooting and Testing Pocket Guide includes updated information on testing and troubleshooting lighting systems, expanded information on diagnosing power quality problems, and a new chapter on thermographic diagnostic tools.
Scope of this Book
Electrician's Troubleshooting and Testing Pocket Guide covers the use of digital multimeters (DMMs) and other testing equipment to troubleshoot electrical and electronic circuits used for power and control applications. In general, it concentrates on traditional electromechanical and inductive equipment found in commercial and industrial occupancies - motors, transformers, lighting, and power distribution equipment. In general, this guide does not cover testing and troubleshooting of the following types of equipment and systems:
Communications systems. The use of network cable analyzers, optical time domain reflectometers (OTDRs), optical power meters, and other equipment used for testing and troubleshooting communications systems such as telecommunications, computer local area networks (LANs), and outside plant fiber-optic installations are outside the scope of this publication.
Electronic components and systems. This book touches on testing of electronic components such as resistors, small capacitors, and diodes. However, the broad subject of troubleshooting electronic components and circuits using digital multimeters and other portable test equipment is covered in much greater detail in Electronic Troubleshooting and Repair Handbook by Homer L Davidson (1995).
