We are using 240V which is different from North America 110V.
How do we comply with the below requirement of Para 6.2.1 of ANSI/ESD S6.1?
Please recommend the equipment and test setup for testing on the below Para 6.2.1 of ANSI/ESD S6.1.
“6.2.1 Equipment Grounding Conductor
The impedance of the equipment grounding conductor from a receptacle (power outlet used for establishing the AC equipment ground) to the neutral bond at the main service equipment panel shall not be greater than 1 ohm”
Hello and welcome to the forum,
ANSI/ESD S6.1 is a North American standard and is based on the electrical code for the USA. Depending on how your electrical system is setup, the measurement could be the same but the impedance could be different.
If your country has a hot, neutral and ground connection, the equipment to measure ground impedance is the same. There are many suppliers such as the Prostat PGT-61-164 or the SCS Ground Pro meter that can make these measurements.
I would recommend that these measurements are done by a qualified person. These measurements are only needed when the area is first qualified. It does not have to be repeated as part of a compliance verification program.
