The facility electrical ground
grid must :
- efficiently
dissipate lightning surge energy that may arrive via down
conductors.
- efficiently
dissipate electrical surges and "faults" to minimize the
chances of injury from either "step potentials" or "touch
potentials"
- provide a
stable reference for electrical and RF circuits at the
facility to minimize noise during normal operation.
- be properly
bonded to eliminate earth loops and differentials under
surge conditions.
We have industry
leadership in bonding and electrical
grounding
technologies :
- ERITECH
UL-listed ground rods and clamps
- CADWELD
UL-listed exothermic molecular bonding technologies for
permanent connections
- GEM and Earth
Enhancing Compounds lower ground impedance and resistance
