Ground
Potential Rise (GPR) analysis is one of
the most sought-after services in the
industry today. In order to protect the
personnel and the valuable technology
used today, GPR analysis is required by
most electric utilities and Telco companies
when operating in high-voltage environments.
E&S Grounding Solutions offers two
types of GPR services to meet your needs:
the GPR Calculation,
and our premiere service, the GPR
Study.
GPR Calculations provide
all the data required for T-1 line applications
including the total fault current, GPR
voltage, X/R factor, and the 300-volt
line. The E&S GPR Calculation Report
includes printouts from the custom computer-modeled
simulations along with photos of your
site. All the information you’ll
need to get your T-1 lines approved. Fast!
The premiere engineering service offered
by E&S is the GPR Study.
This study includes all the information
in the standard GPR Calculation,
and a full analysis of the Step &
Touch Voltages present at your site. The
E&S GPR Study additionally
provides all the structural design recommendations
needed to eliminate any potential electrical
hazards. Let E&S help you protect
your personnel and equipment from the
hazards of operating in high-voltage environments!
