DC SPD applied to the Din rail type protects the DC electric system from surge. Also, the system allows replacement of the protective element (MOV), ensuring convenience and reduced cost. However, as only the protective module is provided, other components should be added when the system is installed in accordance with the site condition.
Operating voltage Uc Depending on the system earthing arrangement, the maximum continuous operating voltage Uc of SPD must be equal to or greater than the values shown in the table in Figure 1. Fig.1 – Stipulated minimum value of Uc for SPDs depending on the system earthing arrangement (based on Table 534.2 of the IEC […]
The main objective of the electrical installation protection system is to limit overvoltages to values that are acceptable for the equipment. The electrical installation protection system consists of: =one or more SPDs depending on the building configuration; =the equipotential bonding: metallic mesh of exposed conductive parts. Implementation The procedure to protect the electrical and electronic […]
Surges may be caused by an indirect lightning strike but, the majority are caused by equipment being turned on or off within a facility. These surges damage components costing money to repair or replace as well as create unplanned downtime resulting in unfulfilled orders, missed deadlines, unreliable systems and/or dangerous situations. The GHX Surge Protective Device (SPD) Series for […]
