Technical Parameters
System Parameters (take one load bank as examples) | |
Rating voltage/frequency | Three phases 690VAC 50/60Hz. It can be used for voltage less than 690V. |
Load bank constitution | Apparent power 5500kVA, resistive power 4400kW, inductive power 3300kvar. Each load bank can divided into 2 sets (apparent power 2750kVA, resistive power 2200kW, inductive power 1650kvar) which can be operated individually, each load bank has circuit breaker which can be individually controlled, there is interconnection switch for two load banks to make each load bank capable of parallel, test, collect data, form report and print, etc. |
Load resolutions (one unit) | Resistive load circuit 1: totally 19 steps, 1,2,2,5,10,10,20,50,100,200,200,200,200,200,200,200,200,200,200(kW) Inductive load circuit 1: totally 17 steps, 1,2,2,5,10,10,20,50,50,100,200,200,200,200,200,200,200(kvar) Resistive load circuit 2: totally 19 steps, 1,2,2,5,10,10,20,50,100,200,200,200,200,200,200,200,200,200,200(kW) Inductive load circuit 1:totally 17 steps, 1,2,2,5,10,10,20,50,50,100,200,200,200,200,200,200,200(kvar) |
