IEC 61000-4-10
Damped oscillatory fields mainly are related by operation of high voltage bus-bar isolators. Field strength of up to
several 100 A/m can be detected.

Two different oscillation frequencies are required:
- 100 kHz with a repetition rate of at least 40 Hz
- 1 MHz with a repetition rate of at least 400 Hz
Damped Oscillatory Generator (OCS 500N6)
100 kHz and 1 MHz oscillation frequency of max. 2,5kV peak voltage. The test pulses are coupled to the lines via
coupling/decoupling networks. The minimum repetition rate is at least 40 Hz (100 kHz) and 400 Hz (1 MHz).
