Importance of correct grounding

Why connect ashore?
A poor quality ground not only contributes to unnecessary downtime, it is dangerous and increases the risk of equipment failure. Without an effective grounding system, we could be at risk of electric shock, not to mention instrument errors, harmonic distortion problems, power factor problems, and a number of possible intermittent errors. If fault currents do not have a path to ground through a properly designed and maintained grounding system, they may encounter unwanted paths that could end up injuring people. The following organizations provide recommendations and standards to ensure safe grounding:
Earth dams protect both equipment and people from dangerous potential differences.
The earth dam is a fundamental element of any electrical installation. According to the Spanish Low Voltage Electrotechnical Regulation:
“The grounding is established mainly in order to limit the voltage that, with respect to ground, the metallic masses may present at any given time, ensure the performance of the protections and eliminate or reduce the risk posed by a breakdown in the electrical equipment used “(Complementary technical instruction 18).
The objectives of a low voltage earthing system are as follows:
• Improve signal quality by minimizing electromagnetic noise.
• Provide safety to people by limiting contact tension. • Protect the facilities by providing a low impedance path. • Establish a reference potential equipotentializing the system.
