• Overview of Grounding and Noise Reduction for Control Equipment (TI21C)


    Length: 1 day
    CEU Credits: 0.7
    Course Hours: 8:00 a.m.-4:00 p.m.
    Certification of Completion: A Certificate of Completion indicating the total number of CEUs earned will be provided upon successful completion of the course.


    This course provides an understanding of grounding, both from an electrical systems relationship and from an instrument loops relationship. The purpose of grounding and electrical systems, grounding for safety, signal noise, signal wiring systems, and methods used to reduce noise will be covered.

    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 | Earth Ground
    • Considerations Relevant to Grounding and Protection from Electrical Shock
    • Techniques of Grounding Wye and Delta Transformers
    • Methods of Grounding Electrical Systems 
    • Isolated Grounding and Resistance (Impedance)
    • Ground Loops in Instrumentation Systems 
    • Noise:  What is Electrical Noise | What is Interference
    • How is Noise/Interference Transmitted
    • Methods of Shielding and Grounding of Instrument Systems to Reduce Noise/Interference
    • Power Quality for Electronic Equipment: Need for Power Conditioners | UPS Systems, and Surge Suppression Devices
    • Power System Harmonics: Their Cause and Effects | Measuring Total Harmonic Distortion and Pinpointing Various Sources of Harmonics

    Classroom/Laboratory Exercises:

    • Check body resistance and compare results
    • Measuring Total Harmonic Distortion
