For abbreviations list, and schematics and wiring diagrams refer to the section Schematic And Wiring Diagrams in this manual.Ammeter-Voltmeter Phase Selector Switch
The ammeter-voltmeter phase selector (AVS) switch has four positions. Positions 1, 2 and 3 allows the operator to check generator output current and voltage for each of the phases 1, 2 and 3 respectively. AC current and AC voltage are checked on the AC ammeter (ACA) and AC voltmeter (ACV) respectively. There is no reading when the AVS switch is in position 0.AC Ammeter
The AC ammeter (ACA) gives an indication, in amperes, of the current from each phase of the generator to the load. The AVS connects the ammeter to the current transformers (CT1, CT2 or CT3) on phases (T1, T2 or T3) respectively. The CT's transform the actual line current, in its respective phase lead, to a level (approximately 0 to 5 amperes) within the input range of the ammeter. The ammeter is calibrated to give an indication of the actual current flow in one phase of the generator.AC Voltmeter
AC voltmeter (ACV) shows the potential difference (voltage) between phases T1-T2, T2-T3 or T3-T1 at positions 1, 2 or 3 respectively of the AVS.Frequency Meter
The frequency meter (FM) shows the
