The TN-S or TN-C-S system is an electrical configuration where the neutral and grounding wires are separated at the source to ensure a reliable grounding connection. This setup is typically linked to transformer grounding, which helps minimize cable breakage and L-PE faults. However, this system can be relatively expensive due to higher costs associated with cables, installation, and ongoing maintenance.

CNKA3 phase ac surge protection device Basic components

1  The discharge gap, often referred to as the protective gap, typically consists of two metal rods spaced apart at a specific distance and exposed to air.

2  A gas discharge tube comprises a pair of separated cold cathode plates, sealed within a glass or ceramic tube filled with an inert gas, such as argon.

3  A varistor is a nonlinear resistor made of metal oxide semiconductor, primarily composed of ZnO, and its resistance is highly sensitive to voltage changes.

4  The suppression diode serves as a final protective component in multi-level protection circuits, offering clamping and voltage limiting functions, along with advantages like low clamping voltage and rapid response time.

5  A choke coil is a common mode interference suppression device that utilizes ferrite as its magnetic core.

6  The 14-wavelength short circuit breaker is a microwave signal surge protection device developed based on lightning wave spectrum analysis and the standing wave theory of antennas and feeder lines.
