<p>The circuitry is is for residential and industrial needs. Itabolishes any losses caused by abuser subscribers. The circuitryconsists of a DC relay (2) the winding (1) of which is shunted toa filtering capacitor (3) and the first end of which is connectedin series to the positive pole of a rectifier (4) and limitingresistor (5) connected to the first end of contact (6) of relay(2) and connected to first jack (7). The second end of contact (6)is coupled to the first end of a fusible plug (8) and is connectedto second jack (9). The second end of fusible plug (8) isconnected to third jack (10). The circuitry is coupled to astandard electric meter including first (13), second (15) andthird (17) terminal, voltage coil (14) and current coil (16).5 claims, 6 figures</p> |
