"This class was great. I have a much better handle on the subject of grounding and noise. Keep up the good work." ~Newell Collins, Technical Specialist-Instrumentation
This course provides an understanding of electrical grounding from an electrical and instrumentation loop relationship. It also covers grounding for personnel/equipment protection as well as for electrical noise. Signal wiring and noise reduction methods are also presented. The material assumes the student has a basic understanding of electrical principles and signal wiring. The National Electrical Code (NEC) is referenced throughout the course.
You will be able to:
- Discuss the relationship between earth ground to electricity and electrical shock
- Explain why some electrical systems are connected to earth ground
- Use the National Electric Code (NEC) as standard for grounding instrument systems
- Illustrate how people become part of an electrical circuit and how to avoid it
- Define what a ground loop is
- Compare noise and interference and how they are transmitted
- Identify instrument signal wiring and conductors
- Use methods to reduce instrument noise
- Identify the effects of harmonics on power systems\\, control systems\\, and computers
You will cover:
- Grounding: NEC Definitions | Requirements | Grounding vs. Grounded Conductor | What are Earth and Isolated Grounds? | Bonding Requirements | Grounding Methods | Ground Loops | Lightning Affects on Electrical Systems and Grounding Systems and How to Help Protect Devices | Electrical Shock
- Electrical Noise: Noise vs. Interference | Radiated, Capacitive or Inductive Coupled, or Conducted Noise | Identifying the Source, the Path, and the Target of the Noise So It Can Be Controlled | Types and Paths of Signal Wiring | Ground Loop Generated
- Powering Sensitive Equipment: Power Quality | Voltage and Current Disturbance Wave Forms | Surge Protection Devices and Characteristics | Power Conditioners | UPS | Circuit and Equipment Affects of VFD/non-Linear Power Supply Harmonics
- Review the effects of various levels of electrical current flowing through the human body
- Use a circuit tester to understand how a GFCI works by checking circuits for improperly terminated leads
- Measure harmonic voltage distortion using a digital power analyzer
