The TT power supply system refers to a protection system in which the metal casing of electrical equipment is directly connected to ground; it is known as a protective grounding system, or TT system. The first symbol, T, indicates that the neutral point of the power system is directly grounded ； The second symbol, T, indicates that the exposed metal conductive parts of the loaded equipment, which are not in contact with live parts, are directly connected to the ground, regardless of how the system is grounded.
