1_a1 1_a

V Series Impulse Voltage Test System is a sophisticated design used to generate impulse voltages from 1400 KV to 6000 KV simulating lightning impulses and switching surges with energies up to 900 KJ and considers all requirements of industry, research & development centers, educational institutes and third party test labs.

Features:

  • Low internal inductance ensures high efficiency.
  • Easy & quick reconfiguration to meet different testing requirements. Front and Tail resistors being of same length can be interchanged thus allowing more       flexibility and wider range of load testing.
  • User friendly operation through computer controlled hardware.
  • Equipped with wave shaping resistors for performing full lightning, lightning chopped and switching impulse tests on wide range of loads. Special resistors       can be supplied for any impulse shape or load testing.
  • Automatic steel & insulating tape grounding device and security grounding system.
  • Alarm annunciation to display all fault conditions.
  • Filtered clear, hot air is constantly supplied through the enclosed sphere gaps while the system is operational to reduce misfires.
  • Reliable, accurate and fail safe triggering circuitry.
  • Load range can be extended using Glaninger Circuit, overshoot compensation, termination resistors and special wave shaping resistors.
  • The electronic measurement and control devices are designed and manufactured to meet electromagnetic compatibility requirements of electronic devices      in high voltage test bays which ensures trouble free operation.

Impulse Dividers

IDI Series Impulse Voltage Dividers (up to 6000 kV LI) are equipped with internal damped resistance. These impulse voltage dividers can be used to measure full lightning impulse voltages, front & tail chopped impulse voltages, switching impulses and AC voltages. They meet all requirements of IEC 60060-2, in particular those with respect to measuring accuracy and step response. Furthermore, all HV tests are carried out in accordance to the applicable IEC 60060-2 requirements (up to the limits imposed by our test system & premises). They can be used as a basic load for impulse voltage generators.

Multiple Chopping Gaps

MCG series multiple chopping gap is used to chop lightning impulses on the front and/or on the tail. It also serves simultaneously as a load capacitor for the impulse generator and allows excellent reproducibility of the chopping time and does not distort the wave shape until the chopping point. The sphere distance is automatically adjusted and operated by the WV 23 Impulse controls.
