SquareTrade © AP6.0 K-7 PHASE SEQUENCE INDICATOR BY KNOPP #RARE# NEW IN BOX a.imagelink {color:#a4a4a4;} a:hover.imagelink {color:#a4a4a4;} a:visited.imagelink {color:#ffffff;} a.imagelink img.auctionimage { border: 2px solid #a4a4a4; } a:visited.imagelink img.auctionimage { border: 2px solid #ffffff; } K-7 PHASE SEQUENCE INDICATOR BY KNOPP #RARE# NEW IN BOX. Leads are color-coded and 36 inches each • Operates from 25-60 hertz and 60-600 volts. Positive, Straightforward Sequence Indication is Provided over a wide range of voltage and frequency by direction of rotor rotation. No need for range swithching or terminal changing Also indicates an open phase. The Knopp Phase Sequence Indicator includes a three-phase induction motor having an aluminum-disc rotor mounted for free rotation on a cushioned glass-hard bearing and having field windings placed at 120 geometrical-degree intervals about the rotor axis. One terminal of each winding is extended beyond the case to a distincity colored conductor and to a lettered test clip for attachment to one conductor of the tested system; and the second terminal of each winding is connected to one of three contacts of the insulated protector -switch. The protector-switch must be held closed to energize the windings and is so arranged that accidental or even continuous closure of the switch is unlikely. The flexible cable withstands severe handling and is intended for suspending the instruments from the line wires or terminals with the test clips. The free ends of the conductors are shorter than the sheathed portion so that, when the instrument is suspended, a detached clip cannot contact the operator while the switch is closed. Since the cable is anchored in the sealed housing, clockwise rotation of the rotor always means that the phase order of the tester terminals is that of the marks A, B, C, on the clips attached therto. THE K-7 TYPE IS AVAILABLE ON ORDER FROM THE MILITRY ONLY. VERY RARE. Certain images/photos are the copyrighted property of JupiterImages and are used with permission under license.
