1. Lightning protection starts with grounding fractions. The housing of the radar level meter is very similar to the control cabinet, special console, power cabinet, etc. The housing should be adjacent to the common flat steel.
The instrument task power supply, e.g. 24 V negative terminal, is connected to the instrument earth and the input and output earth of the totalizer to form an equipotential.
The earthing of intrinsically safe earth, safety grids, suppression grids, and safety devices should also consider whether the instrument reference point can form an equipotential when adjacent to each other.
2. Intelligent instrumentation power supply lightning protection should not be ignored. Intelligent instrumentation installed anti-surge protection, paying attention to the fractional elements or surges, to ensure that the instrumentation does not exceed the voltage limit. A surge attenuator is mainly used to induct lightning surges in thunderstorms when the overload current is collected to the ground.
3. For smart instrumentation equipped with trust channel surge devices, not only to ensure accurate, stubborn, and flexible dynamic transmission but also to release over-voltage surges to the ground during thunderstorms to ensure safe transmission.
4. Regularly on the smart instrumentation of the power supply fractional grounding, convergence bar, grounding body, surge device, power supply lightning fence, etc. to find and repair, and timely replacement.
