‘Lightning & Grounding Electrical Protection Seminar 
for Towers and Equipment Buildings

{This is the only training available in the country which provides methods for grounding and protecting tower and equipment building from lightning induced Ground Potential Rise (GPR)}


This two (2) day training seminar with manuals will be suit-cased to your location for $675 per attendee with a minimum of ten (10) attendees plus instructor travel expenses.  Request a firm quote at


A three (3) day seminar (not shown) is offered that will also include the electrical protection requirements for equipment in a power station environment at $800 per attendee with a minimum of ten (10) attendees plus instructor travel expenses.


Training Seminar outline:


Day One (1):


I. Ground Impedance testing and calculations

II. Grounding requirements using radial capacitive grounding systems for lightning and Single Point Grounding (SPG): Electrode Design for Grounding Systems

III. Placing Ground Rods, Radial Spiders and Bonding to Metallic Objects, fences, etc.

IV. Grounding Conductor Requirements in Equipment Building , MGB, SPG, HALO, RF Grounds

V. AC Power Grounding Electrode

VI. Transient Voltage Surge Suppression (TVSS)

VII. COAX Cable and Bulkhead Panel for Tower Coax, Ice Bridge , etc.

VIII. Communication Facility Isolation from a Lightning Induced Ground Potential Rise (GPR)

IX. Equipment Building Lightning Protection System

X. Personnel Safety


Day Two (2):


Field trip to Tower Site to test soil resistivity and grounding system, conduct a grounding and electrical protection survey.  Develop a list of grounding and electrical protection discrepancies that may require correction to prevent damage from lightning strike energy.
