Each of four previously untested TVT samples to be connected to an ac
power supply having an open circuit voltage equal to Uoc. The power supply
is to incorporate a series variable resistor that can be adjusted to obtain the
short-circuit values (Isc) respectively.
The four samples are to be energized for 7 hrs, or until current to, or body
temperature attain equiubrium, or until the sample becomes disconnected
