SH-H, SH-Q, SH-R Shunts Impulse Current Measuring Shunt Sets These shunts are used for the measurement of impulse currents in high-voltage test labs. The wave shape of the measured current can be displayed on a Haefely digital impulse analysing system e.g. DiAS733, HiAS743 or DMI 551. Design The shunts consist of a metal cylinder with coupling flanges and coaxial measuring connector. Three different construction types are available depending on the current value to be measured. Set of Sleeve Shunts SH H Interchangeable low-inductive resistor-sleeves can be built into the metal cylinder. A set consists of one cage and three sleeves of 2, 5 and 10 Ω. The standard repetition rate allows measuring impulse currents up to 250 A (voltage drop 500 V), and at reduced repetition rate up to 500 A are possible (voltage drop 1000 V). Set of Cage Shunts SH Q Each resistance value is a separate shunt. A set of cage shunts consists of three shunts of 1, 0.47 and 0.1 Ω. The standard repetition rate allows measuring impulse currents up to 5000 A (voltage drop 500 V), and at reduced repetition rate up to 16000 A are possible (voltage drop 1600 V). Set of Tubular Shunts SH R Each resistance value is a separate shunt. The standard repetition rate allows measuring impulse currents up to 100 kA (voltage drop 500 V), and at reduced repetition rate up to 200 kA are possible (voltage drop 1000 V).
