Presentation Description

SFR-L series capacitor modules are integerated with some functions of power meters which can measure conventional electrical parameters of the power system. SFR-L series capacitor modules have many protection functions such as capacitor internal temperature protection, grid harmonic content protection, over current protection, over voltage protection and three phase unabalance protection which make them more voltage. https://sfere-elec.net/product/SFR-L-Low-voltage-power-capacitor-71.html

Compliance with standards GB/T 15576-2008 Low voltage reactive power compensation assemblies GB/T 22582-2008 Power capacitors—Low-voltage power factor correction banks JB/T 9663 -1999 Low-voltage reactive power automatic compensation controller 1 . 2 . Product description SFR-L series low voltage intelligent power capacitor modules take two △ type compensation capacitors or one Y type compensation capacitor as main body and are highly integrated with compound switch microprocessor and other function modules. Due to their modularity structure they have such advantages as small volume and easy maintenance. SFR-L series power capacitor modules are mainly used for reactive power compensation in the fields where harmonics are not very serious. They are suitable for local compensation dispersion compensation and centralized compensation. This series of products adopt double zero-crossing switch technology to make sure there is no over voltage or high inrush current during capacitor switching so as to prolong capacitor life and switch life. SFR-L series capacitor modules have many protection functions such as capacitor internal temperature protection grid harmonic content protection over current protection over voltage protection and three phase unbalance protection which make them more reliable. This series of products adopt a using method of building blocks. If many capacitors are used one of them will become the master automatically and others will become slaves. Then a reactive automatic control system is built. If some of the slaves fail they will exit the system automatically without influencing other slaves if the master fails it also will exit the system automatically and then another new master appears and a new control system is built. Meanwhile SFR-L series capacitor modules are integrated with some functions of power meters which can measure conventional electrical parameters of the power system
