Ground Potential Rise Studies

Understanding the hazards posed by high voltage fault conditions to personnel and equipment is becoming critical as more sites utilize high voltage enviornments for locations such as communication towers. 

Personnel and equipment require protection from the hazardous and damaging effects of Ground Potential Rise (GPR) and Step-Touch Voltages. Close coordination and cooperation are needed from all involved parties (Utility, Communication Company, and Engineering Firm) from the earliest design stages of the site. We have a strict adherence to industry standards of design and recommended practice, such as IEEE Std. 487 and Std. 387, and is critical in designing a properly protected site that will ensure the safety of the personnel and proper operation of the equipment.

Unfortunately, many communications site providers are simply unaware of the hazards of installing equipment in these high voltage environments and many utilities take for granted that the proper design considerations for safety have been met by the installers of the sites on their property. Understanding and developing a proper plan for the safe installation of communications sites within the high voltage environment is, and will grow to be, a critical design component in the future of the utilities and the communications companies.

Lyncole's Ground Potential Rise Process

Lyncole performs Ground Potential Rise studies for clients when they are installing a facility grounding system in or near a high voltage environment. These studies use the fault clearing time, available fault current, and other factors to calculate the ground potential rise (GPR) and step/touch potentials. Lyncole engineers perform these calculations in order to determine what measures are required to make the site safe for workers and the public alike. A detailed report with charts (right) depicting the site characteristics are included.
