maajärjestelmät
Maajärjestelmät, also known as earthing systems or grounding systems, are crucial components of electrical safety and functionality. They define how electrical systems are connected to the earth. The primary purpose of a maajärjestelmä is to provide a safe path for fault currents to flow to the ground, thereby protecting people from electric shock and preventing damage to electrical equipment.
There are several common types of maajärjestelmät, often denoted by prefixes that describe the relationship between
