Repetitive damped oscillatory waves are phenomena associated with the opening and closing of high voltage (HV) busbars in high voltage (HV) and medium voltage (MV) power transmission stations. The physical environment influences the fundamental oscillation frequency and repetition of the impulses. The most common type of switch used in power distribution is an air insulated type which has been measured as generating damped oscillatory impulses up to 1MHz with a repetition rate up to 400Hz. Damped oscillatory impulses up to 1MHz are termed “Slow Waves”.

MIG-OS-OS1

The “classic” damped oscillatory wave generator for IEC, EN and ANSI applications. The slow waves are available through either balanced differential or grounded outputs. The 100kHz and 1MHz waveforms can be programmed up to 3000V. This generator is ideal for applications requiring only the slow waves.

MIG-0603OSI

A combination of slow wave generator up to 3000V, combination wave generator up to 6000V/3000A and 1.2/50μs voltage impulse up to 6000V with 0.5J energy content. All impulses can be used for IEC, EN and ANSI applications.

MIG-OS-OM

A combination of the “classic” damped oscillatory wave generator for IEC, EN and ANSI applications. The “slow waves” are available through either balanced differential or grounded outputs. The 100kHz and 1MHz waveforms can be programmed up to 3000V. Apart from the voltage impulses, this generator has outputs for magnetic field testing using the 1m x 1m antenna.
