Impulse Current Test Systems-Sa Type
Impulse Current Test Systems-Sa Type
Product Code : 14
Product Description
SA type impulse current generator can generate different types lightning impulse current shapes such as 4/10μs, 8/20μs, 120μs, 30/80μs, 60/100μs , long duration current according to IEC 60099-4. Modifications can be applied according to the request of our customers.

This type of test system is especially to test the metal oxide surge arresters.

Features and Benefits:

  • Reliable and precisely controlled triggering unit by power pulse;
  • Protective earthing system for safety;
  • Shape resistors designed for low inductance and connected by easy joint;
  • Specially designed circuit available for different shapes;
  • Easy operation with the automatic control based on PLC module;
  • Special solutions to customer’s problem and special requirement.

Applications:

  • Residual voltage test of surge arresters;
  • 4/10μs impulse current test of surge arresters;
  • Long duration impulse current test of surge arresters
