Measuring waveforms of 20Khz Inverter based welders and UPS

Post by Guest »

Can these PC based scopes be used for measuring waveforms under load conditions of 3 phase 415V Inverter based welders using 100/150 or 200A IGBT's? And at the secondary Diode (upto 400A and 30~85V). What are the recommended parts to buy alongwith the scope. Are the scopes Isolated to prevent device damge?

Hello Guest,

You may use most of our oscilloscopes (http://www.picotech.com/oscilloscope.html) with a suitable current clamp for the measurements that you require.

Our own range of current clamps do not cover the combination of frequency and current that you require but, you may well find suitable clamps elsewhere.

Would appreciate your recommendations on the probes to be used for this application mainly voltage measurements.
