Paul,
This question has arisen because, according to our electrical engineers, there is an ~1% error when using the analog output of the LKCO or NXCT F3 transducers. And the NXCT people confirm that too. If you hook it up to the oscilloscope that's roughly another ~1 per cent of error due to the scope's ADC. So you don't have 0.1% anymore, it is ~2%! And that's 3000 Amperes for the 150 kA transducer. The NXCT representative says that the digital output is more accurate (no 1% error). I think the same thing can be applied to the LKCO sensor you are currently using.
Regarding HV resistors - which ones do you use (what make?) Thanks. -- Best regards, Pavel Maslov, MS Controls Engineer at Pulsed power Lab Efremov Institute for Electro-Physical Apparatus St. Petersburg, Russia Mobile: +7 (951) 672 22 19 Landline: +7 (812) 461 01 01
