AMETEK CTS OCS 500 N6 series
Manual for Operation V 5.24 32 / 80
Damped Oscillatory 100 kHz or 1 MHz as per IEC 61000-4-18
This phenomenon is representative of switching of isolators in HV / MV open-air stations, and is particularly
related to the switching of HV bus-bars, as well as of background disturbances in industrial plants.
Verification as per IEC 61000-4-18:
Open circuit
V peak 250 V – 2500 V ±10 %
Rise time first peak 75 ns ±20 %
Oscillating frequency 100, 1000 kHz ±10 %
Decaying of peak 5-1 > 50% of peak 1
Decaying of peak 10-1 < 50% of peak 1
Repetition rate at least 40/s for 100 kHz
at least 400/s for 1 MHz
Short circuit
I peak (200) 1.25, 2.5, 5, 10A ± 20 %
Source impedance 200 20 %
Operation
This menu offers different test routines for Damped Oscillatory testing. The menu structure is identical for both,
the 100 kHz and the 1MHz damped oscillatory.
