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).
