Analog Phasing Testers for Transmission Circuits

To easily determine phase relationships, these Chance Phasing Testers read approximate voltage (line-to-line or line-to-ground) on transmission circuits.

The testers consist of two high-impedance components encased in fiberglass poles, each with an end fitting threaded for interchangeable hook probes. A 22-foot-long insulated flexible cable from the voltmeter stores on a reel on the other pole.

Three complete kits offer a choice of voltage ranges for specific system applications. Each kit includes a pair of 1-1/4″-diameter insulated handles for proper working clearances.

Individual items listed in each kit’s bill of materials may be ordered separately by reference numbers given.

Phasing Voltmeter Tester

The phasing voltmeter tester allows line personnel to determine, in the field, the operating condition of the Chance instruments named above.

The tester uses each instrument’s own meter to display its operating condition, and plugs into the jack on the instrument. Meter readings are noted when the tester’s clip is contacted to each of the instrument’s two terminals, and the tester’s polarity switch is in both of its positions.

If all four readings are within two units, the instrument is in proper working order. Pulling the plug from the jack automatically disconnects the tester’s battery. The 9-volt battery, furnished, usually lasts one year, and is easily replaced.

The tester has durable and compact fiberglass housing that will withstand the abuse of field applications.
