Product Description General InformationThis impulse test system is used for carrying out full wave lightning impulse voltage tests on HV apparatus such as clearance, bushings, capacitors, switches, power transformers (capacity below 5000kVA), CT/PT at 35kV or below.Specifications Nominal voltage: ±300kVRated energy: 30kJ(5kJ/stage)Impulse capacitance: 0.666μFNumber of Stage: 3Charging voltage per stage: ±100kVRated level capacitance: 2μF (each impulse capacitor 2μF at 100kV, total 3pcs)Output voltage waveform: (Load capacitance is 300-3000pF) T1= 1.2μs±30%, T2=50μs±20%, peak voltage error≤3% standard lightning impulse voltage full wave.Impulse voltage waveform parameters and error are accorded with national requirements of GB311.1and GB16927.1 standard and IEC standard.Output Voltage Efficiency: Standard lightning wave ≥90% when load capacitance is below 1000pF, standard lightning wave ≥85% when load capacitance is below 2000pF.Locking range: level voltage is within the range of 20%-100% of rated voltage, positive and negative locking range no less than 25%.Out-of-control rate of synchronous discharge: <5%Min. output voltage: ≥±10% of rated voltage.Instability of charging voltage: <±1.0%Continuous time: Above 2/3 of rated voltage, continuous working when charge anddischarge once every 120s. Below 2/3 of rated voltage, continuous working when charge and discharge once every 60s.
