PHASE TESTER
A portable equipment for easy and safe phase sequence determination and comparison, as well as AC, phase-to-phase, or phase-to-ground voltage readings in 1 kV to 80 kV transmission and distribution circuits.
The basic unit is comprised of a 1 kV to 16 Kv direct reading galvanometer and a 6.50 m reel with hielded cable, mounted on two RITZGLAS® sticks, which are high impedance units required for readings on the instrument.
Voltages above 16 kV require extensions (RH1876-4 for 48 kV and RH1876-2 for 80 kV). These extensions are coupled to the threaded end of the instrument stick for indirect reading, that is, x3 full scale for 48 kV and x5 full scale for 80 kV.
A pair of extensions must be used for 48 kV (RH1876-4) and two pairs for 80 kV (RH1876-2). Length of each unit: 630 mm.
The Calibration Device (H1876/B-AFT) is designed to calibrate the phase detector before use, especially after a long inactivity period. It generates a digital signal to the phase detector so that the user can compare the galvanometer reading with the value on the calibration device display.
This Calibration Device must be ordered separately.
Power supply: 9V battery.
