Instrument selection for touch/leakage measurements need to consider the intended use. Commercial instruments that are used for units scoped for I.T. and lab equipment could also be used for Type Tests.
For various reasons, we (the engineering lab) use home-grown stuff, while the factory typically uses commercial instruments. And I do recommend the commercial 'all-in-one' safety test boxen for the production people. In addition to the multiple years of the PSTC discussions on this subject, I have seen numerous articles on this subject. In particular, note the P.E. Perkins article, "Touch current comparison data".

Most types of leakage meters I have seen are equipped with a single internal network, limiting the equipment to a single type of test. Are there other alternatives, which provide for changing to different impedance models? Or are most labs using small hand-built networks and digital RMS meters? I would like to provide flexibility in the types of impedance networks that could be tested, including the old-school UL/CSA, and IEC60990. Does anyone have any recommendations? Please feel free to contact me, off-line if desired. Thanks in advance. Best Regards, Brian Ceresney - This message is from the IEEE Product Safety Engineering Society emc-pstc discussion list.
