Lightning Protection System Testing Procedure

The resistance between these components and the lightning protection system shall be less than one 1 ohm.

Lightning protection system testing procedure.

Our property has a lightning protection system installed. Afp 91 38 6 2 3 states that the electrical test procedures. Health and safety procedures in the event of flooding. An lpt also includes.

Army 5 and air force 6 documents provide specific lightning protection and grounding systems test procedures. Upon completion of installation after work on expansion modification addition or other changes to the underlying protected structure s that requires disturbing the system nfpa 780 b 5 after relocation of components supporting the system. Each individual earth grounding point and its conductors are electronically tested for resistance to ground. The complete lightning protection system measured at any point should not exceed 10 ohms.

When testing earth electrodes in lightning protection systems it is important to remember that there may be multiple connections to the system. What is lightning protection testing. With the test clamp disconnected the resistance of each individual earth should be no more than ten times the number of down conductors in the complete system. What are the requirements for testing and inspecting of the system.

The complete table of inspection and testing activities that shows each activity to be performed in order to make sure that the installed earthing lightning protection systems are compliant to the project s specifications and requirements the reference to be followed acceptance criteria responsible personnel related checklist from item 3 below the required level of interference from each party contractor consultant third party such as. A premises safety audit has identified that this has never been fully inspected or tested. To ensure thorough and correct maintenance a lightning protection test checklist should be followed. By law certified testing must occur within a two year time frame.

The purpose of this procedure is to define the step by step method to implement the correct practices for the precommissioning testing commissioning of lightning protection system through the guidelines contained herein so as to ensure that the job execution complies with the project requirements and serves the intended function to satisfactory level. The grounding and lightning protection system shall be given a visual inspection by the engineer during the installation. A lightning protection test lpt involves all lightning conductors and earth grounding installations being visually inspected and tested by a qualified electrical engineer. Inspection survey report review.

Lightning protection system be measured and recorded. The terminated head of each electrode shall be located in a light weight inspection pit. A lightning protection test and earth grid test must be carried out when the installation has been completed and should be done by a licensed electrician. Lightning protection systems should be inspected and repaired as necessary.
