Neptune [india] manufactures nsla 400 series of automatic capacitor panels for centralised power factor correction of loads. The total power of each piece of equipment is divided in several banks managed by a neptune-ducati apfc relay. The latter is sensitive to variations in reactive power and connects or disconnects the banks maintaining the pf of the system at desired value. It is floor mounted and is designed to be used where medium high power is required. The unit is equipped with fsu at the beginning of the power supply. In case of fault, earth fault protection is provided to disconnect the banks. Apart from that, various other features of panel are: auto/manual selection of banks with indication, forced air cooling of banks with axial flow fans, tripping with audio visual indication under high voltage, high temperature, harmonic over load, and low pf condition. Mach smart energy analyzer is filled to check the capacitor current voltage for each phase separately, plus all value added features of mach smart. Rs 232 serial port is provided on the panel to connect it to pc or hand held terminal for data logging. The cabinet has ip-30 protection with gray ral 7035 structure with powder coated finish. Busbars are tinned electrolytic copper with 50 ka breaking capacity.
