The TN-S or TNC-S system is an electrical system in which the neutral and grounding wires are separated at the starting point through a cable to protect the grounding connection. This system is usually connected to transformer grounding to minimize cable breakage and L-PE faults. However, the cost of this system is relatively high, whether in terms of cables, installation, or maintenance.
The discharge gap, also known as the protective gap, is usually composed of two metal rods spaced at a certain distance, exposed to air.
Gas discharge tube is composed of a pair of mutually separated cold cathode plates, sealed in glass tube or ceramic tube filled with inert gas (such as argon).
varistor is a metal oxide semiconductor nonlinear resistor, whose main component is ZnO, and its resistance is very sensitive to voltage.
The suppression diode has a clamping and voltage limiting function, which can be used as the last few protection components in multi-level protection circuits. It has the advantages of low clamping voltage and fast action response.
Choke coil is a common mode interference suppression device that uses ferrite as the magnetic core.
14 wavelength short circuit breaker is a microwave signal surge protection device made based on the spectrum analysis of lightning waves and the standing wave theory of antenna and feeder lines.
