Specifications include, but are not limited to: This specification describes a Three Phase Primary Injection Test System consisting of a three-phase control unit and three load units. Each three-phase output is obtained from a single-phase source with the three-phase controller shifting the outputs of the individual load units by +/- 120 degrees. The load units can also be used individually as three single-phase primary injection units with the single-phase control unit. As single-phase units they must be upgradeable to its maximum power configuration by additional current generation unit(s). The test system shall have built-in digital timer, analog outputs, contact monitoring facilities and measurement inputs. It should also come with control software with built-in test templates and test management facilities for testing for breaker, relay, CT, VT, PT and recloser. The system shall also be furnished with RS-485 port, USB ports for PC communication, and Ethernet port for firmware/software update purposes. The complete system shall be offered with required cabling, built-in handle and wheels so that it can be easily transported.
