5289 100kVA, 10/12* kV Automatic Resonating Inductor for use with MIDAS System The capacitive load range of the MIDAS system can be increased by using this Compensating Reactor (resonating inductor). TECHNICAL SPECIFICATIONS Max. Operating Voltage Frequency Maximum Output Current The 5289 provide an automatic tuneable 15kV, 100kVA inductor coil. It comes into use mainly for power generator on-site testing. Also a separate parallel booster supply for the standard MIDAS system is integrated. Maximum Output Power Inductance range 9 Load tuning range PD Level @ Max. Output Duty cycle at full load The variable inductor is connected in parallel with the capacitive test object Cx. This configuration constitutes a parallel resonant circuit. By adjusting the inductor Lk the resonant point can be balanced. Dimensions WxDxH Weight Operating Temperature Storage Temperature Relative Humidity In this resonant configuration the inductor compensates the reactive power required by the capacitor and only a smaller portion of real power (ohmic losses) is taken from the main supply. This arrangement enables measurement of capacitances bigger than 1F at 15kV. * use additional base load capacitor if load < 250nF 5289 resonating inductor Base load capacitor 400nF Connection cable set MIDAS (3m) Connection cable base load capacitor (20m) OFFICES: Europe Haefely Test AG Birsstrasse 300 4052 Basel Switzerland + 41 61 373 4111 + 41 61 373 4912 sales@haefely.com China Haefely Test AG Representative Beijing Office 8-1-602, Fortune Street No. 67, Chaoyang Road, Chaoyang District Beijing, China 100025 + 86 10 8578 8099 + 86 10 8578 9908 sales@haefely.com.cn North America Hipotronics, Inc. 1650 Route 22 N Brewster, NY 10509 United States HAEFELY HIPOTRONICS has a policy of continuous product improvement.
