The technical parameters of metal oxide surge protective device insulators installed on 35kV lines generally must meet the following requirements: ① Continuous operating voltage (RMS) not less than 40
The hazards of lightning are obvious to all. However, in recent years, with the transformation of power grids, especially the transformation of urban power grids and the construction of substation aut
surge protective device is the abbreviation for what we commonly call a surge protector. It's considered an essential device for lightning protection in electronic equipment. Lightning is a common nat
surge protective device devices are designed to protect against induced lightning strikes, but they don't mention any that can effectively protect against "lightning strikeback voltage" without burnin
First, consider the video signal SPD connected in series to the camera's output: the SPD's top terminals connect to the video line's input and output, and a grounding point that's normally open to the
Surveillance systems primarily monitor incidents that could impact public safety, property, and other emergencies, serving as a basis for post-incident investigation and evidence collection. During th
1. For surge protective device connected in series, all ports marked "output" on the product must be connected to the protected equipment. 2. When grounding surge protector, carefully and correctly in
A typical surge protective device installation should follow these steps: 1) Determine the discharge current path. 2) Mark the conductors that cause additional voltage drop at the equipment terminals.
In harsh power supply environments, circuit design should specifically consider a 3+1 structure. In areas with poor power supply conditions or where the power supply situation is unclear, it is recomm
Alarm Function Selection To monitor the operational status of the surge protective device system, users should promptly notify and replace any damaged surge modules when the protector fails. To ensure
Simply considering the lower the residual voltage for a surge protective device, the better is incomplete and easily misleading. First, the nominal residual voltage values for different products mus
The maximum continuous operating voltage (Uc) of zinc oxide varistor surge protective device (such as TPSB65 and TPSC40) is a key parameter for the operational stability of surge protector. When selec
Even a small surge or peak voltage can ultimately destroy or affect the performance of expensive electronic equipment, such as computers, telephones, fax machines, televisions, audio/video equipment,
Several important parameters of surge protective device are determined as follows: (1) Nominal voltage Un: The rated voltage of the protected system is consistent. In information technology systems, t
