The Greenlee FACT-1 (52087339) Feeder Ammeter Clear Test Set indicates the presence of grounds or short circuits on a primary feeder's three phase conductors or on transformer secondaries. It prevents damage to distribution feeder circuits by detecting ground connections before a feeder is energized.
- Helps prevent fault currents, transformer damage and blown fuses
- Automatically detects incorrect polarity
- Built-in automatic controller performs self test
- Indicates presence of grounds or short circuits on 3-phase conductors of a primary feeder or transformer secondaries
- Alerts user to grounds left in place before circuit is energized
- Helps prevent fault currents, transformer damage and blown fuses
- Easy to use with fully automated test procedure
- LCD display shows instructions, messages and ammeter current
- Internal diagnostics confirm proper operation
- Automatically detects incorrect polarity
- Portable, one person design with rolling case and handle
- Built-in automatic controller performs self test
- Measurement Range: Up to 5A current
- Operating Frequency: 60Hz
- Output: 120V AC
- Dimensions (W x L x H): 21 x 16.5 x 11.5 in. (53 x 42 x 29 cm)
The Greenlee FACT-1 (52087339) Feeder Ammeter Clear Test Set is used to indicate the presence of either grounds or short circuits on a primary feeder's three phase conductors or either grounds or short circuits on transformer secondaries. The FACT-1 prevents damage to distribution feeder circuits by detecting ground connections before a feeder is energized.
Over the course of a maintenance or upgrade program with a number of work sites, dozens of grounds can be put in place over the length of the feeder. When the maintenance or upgrade work is completed, all of these grounds must be accounted for and removed. Failure to remove even one of these grounds before the feeder circuit is reenergized can result in damage either at the location of the ground connection or at the substation where damage can occur to switches, circuit breakers and other equipment. Adjacent circuits will also suffer from the voltage dip or other transients caused by this fault.
The FACT serves to provide a final verification that these grounds have been removed before circuit energization. After the circuit has been visually inspected for grounds left in place and before substation breakers are closed, the FACT is applied to the feeder circuit. The FACT can be applied within the substation or anywhere along the length of the feeder circuit. Unlike simple continuity testers, the FACT can detect grounds left in place and can do so with all of the other equipment connected on the circuit such as transformers, capacitor banks, lightning arresters, etc.
The FACT energizes the circuit at a low secondary voltage and measures the resulting current flow in the circuit. The FACT power supply operates at 120VAC nominal and because it is current limited can be safely connected to any circuit, grounded or otherwise. The FACT includes a built in automatic controller that performs a self test and steps through all three phases, testing each one in sequence. An LCD display shows the condition of each phase and displays any shorts detected. The FACT can differentiate between current drawn by transformers and current resulting from grounds left in place. Any ground left in place on any phase anywhere along the length of the circuit will be detected and displayed by the FACT.
