Automatic Secondary Injection: DRTS6
The DRTS6 is a six-channel secondary injection test set which may be controlled via a remote link to a computer.  It is a lighter, lower-power equivalent to the DRTS66 / DRTS64 and does not have a built-in HMI.  For testing higher power three-phase differential relays, consider the DRTS66.
