Harmonic filter reactors

Neptune India Limited makes harmonic filter reactors that possess properties such as low temperature rise and lower flux density so that it can operate in worst conditions and harmonic overloads. These reactors offer good degree of linearity. These reactors are available with filtering factor of 7 and 14 per cent in 12.5, 25, 50 and 100 kVar rating. Windings of the reactors are made of double enamelled copper wire (rectangular cross section) with temperature class H/180 degree Celsius. Winding supports are made of Nomex 410 aramid paper with temperature class C/220 degree Celsius. Technical specifications: Rated voltage: 3 x 415 V Frequency: 50 Hz Constructional maximum voltage: 1000 V Test voltage: 5000 V Linearity (L> 0.95 x Ln): 200 per cent Ambient temperature: + 55 degree Celsius Winding material: Cu Insulation class: H Temperature sensor (normally closed): 155 degree Celsius Reference standard: IEC 61558-2-20 Features: Core made of grain-oriented cold rolled electrical steel. Vacuum and pressure impregnation (VPI) with high quality varnish. Safe construction, low combustion capacity. Air channels between winding for better air circulation.
