ELV System Installation
ELV, which stands for extra-low voltage, refers to an electrical system with voltage lower than 50V (for alternating current) or 120V (for direct current). In most cases, it is designed in such a manner to keep the voltage within the designated threshold under standard circumstances as well as during single-fault situations. A typical ELV system installation can be further divided into several types including:(1)-Protection ELV (PELV) – connected to earth;(2)Separated ELV (SELV) – disconnected from earth;(3)Functional ELV (FELV) – anthing other than PELV and SELV. You can find ELV systems in numerous devices including CCTV cameras,
fire alarms, and access control panels. One of the main reasons ELV systems are utilized is to reduce the hazard of lethal electrocution. This explains why they are commonly found in places with potential hazards such as aquatic centers and outdoor facilities which are prone to extreme weather conditions.
