According to the IEEE Std 142-1991 and IEEE Std 142-2007 (The Green Book), the communication tower grounding electrode resistance of large electrical substations should be 1 Ohm resistance or less.
A. Grounding system resistance to ground shall not exceed 5 ohms. Make necessary modifications or additions to the grounding electrode system for compliance without additional cost to the Government.
Measure grounding electrode system resistance using an earth test meter, clamp-on ground tester, or computer-based ground meter as defined in IEEE 81. Record ground resistance measurements before
Unexplained noise can creep into station systems where ground systems develop high resistance or noisy connections to ground due to corrosion and oxidation. This is especially true where the station is near salt
This test is performed by connecting the meter leads between the nearest available grounding electrode and the busbar in the Telecom Room. The recommended maximum value for the bonding resistance between these
Different topic about antenna resonance, currents and function. The National Electrical Code, and subsequently your local electrical code does have a grounding requirement for RF installations - NEC 810. The first three
Each Power Circuit Breaker or Power Transformer having a bushing Voltage Transformer on the tank shall have the Voltage Transformer provided with a separate ground lead, independent of the Breaker Frame or
Provide a ground rod near a corner within 6” of the corner in each maintenance hole and handhole. Bond to the ribbon in the maintenance hole.
