    Product Description

    This impulse test system is used for carrying out standard lightning impulse voltage full wave and operation wave tests on HV apparatus such as power cables, power capacitors, clearance, bushings, switch-gear, power transformers and CT/PT at 10kV or below.


    Features

    Main Parameters for System

    • Nominal voltage: ±100kV           
    • Rated level voltage: ±100kV
    • Rated energy: 5kJ
    • Impulse capacitance: 1µF
    • Number of Levels: 1
    • Rated level capacitance: 3µF(each impulse capacitor 1µF at 100kV, total 1piece)
    • Impulse voltage waveform: generated when load capacitance is 300-3000pF.
    • T1=1.2µs±30%,  T2=50µs±20%,  standard lightning impulse voltage full waveform of  peak voltage deviation≤3%;
    • Standard operation waveform 250±20%/2500±60%. These 2 Impulse voltage  waveform parameters and error are accorded with national requirements of GB311.1and IEC60060 standard.
    • Voltage utilization factor: Standard lightning impulse voltage waveform ≥90% when load capacitance is below 1000pF, standard operation impulse voltage waveform≥80% when load capacitance is below 2000pF. 
    • Standard operation impulse voltage waveform ≥70%.
    • Locking range: level voltage is within the range of 20%-100%rated voltage, positive and negative 
    • locking range no less than 25%.
    • Out-of-control rate of synchronous discharge: <5%
    • Min.output voltage: ≥±20% of rated voltage.
    • Instability of discharge voltage: <±1.0%
    • Continuous time: Above 2/3 of rated voltage, continuous working when charge and discharge once every 120s. Below 2/3 of rated voltage, continuous working when charge and discharge once every 60s.
