Abstract
A portable test set for testing the voltage regulators used by utilities in the power distribution industry for regulating a voltage level of electrical power supplied over a transmission line comprises a first electrical lead adapted for connection to the source bushing on the regulator, a second electrical lead adapted for connection to the load bushing on the regulator, and a third electrical lead adapted for connection to the S/L bushing on the regulator. The test set also includes an electrical terminal adapted for connecting a voltage continuity tester between the second lead and the third lead, an electrical terminal adapted for connection to an alternating current source, and an electrical terminal adapted for connection to a voltmeter. A first switch circuit has a first operational state which selectively connects the terminal for the alternating current source to the first lead and a second operational state which selectively connects the terminal for the alternating current source to the second lead. A second switch circuit has a first operational state which selectively connects the terminal for the voltmeter to the first lead and a second operational state which selectively connects the terminal for the voltmeter to the second lead. Other versions of the portable test set are also disclosed.
