AC Type 2 Surge Protector Device SPD Working Principle and Installation

AC Type 2 Surge Protector Device SPD Working Principle and Installation https://lsp.global/type-2-spd/ Type 2 Surge Protector Device (SPD) typically uses a Metal Oxide Varistor (MOV) as its core component and may also include a Gas Discharge Tube (GDT). Under normal voltage conditions, the MOV stays in a high-resistance state and does not conduct current. When a sudden overvoltage happens in the power system, such as from lightning or equipment switching, the voltage exceeds the MOV's rated level. At that point, the MOV quickly changes to a low-resistance state. This allows the excess surge current to flow safely to the ground, protecting the connected electrical devices from damage. Type 2 surge protective devices applications: Industrial buildings Residential and commercial buildings Datacenter Photovoltaic (PV) Systems Radiocommunication 00:07 The Type 2 SPD is installed inside the distribution board near the terminal equipment 00:14 When tension increases, SPD discharges the surge current 00:21 The visible window indicates 'Red', when surge capacity exceeds 00:36 When the red light is on, it's time to replace the surge protective device 00:50 In the distribution box, the main circuit breaker is 100A 01:04 The cross-sectional area of the live and neutral wires should be 2.5 mm2 or above 01:16 The total length of the connections for L1, L2, and L3 should be less than 50 cm 01:23 SLP40-275/3S+1 is suitable for TT and TN-S networks 01:30 SLP40-275/4S is suitable for TN-S networks 01:41 SLP40-275/3S is suitable for TN-C networks 01:53 A professional approach to surge protection will guarantee your electrical installations a long life ---------------------------------------------------------------------------------------------------------------------------------------------------- Since 2010, LSP has been dedicated to designing and manufacturing surge protective devices protecting installations from transient overvoltages that result from switching events and lightning strikes. ---------------------------------------------------------------------------------------------------------------------------------------------------- Wenzhou Arrester Electric Co., Ltd.
