There are components connected between the hot line and the neutral line in the following order (b) front metal oxide varistor(s) line transient voltage surge suppressor having to suppress undesired power spikes;(c) at least one capacitor of predetermined capacitance;(d) at least two chokes in the form of inductor/metal oxide varistor transformers;(e) at least a second capacitor of its own predetermined capacitance;(f) back metal oxide varistor(S) having a predetermined capability. In preferred embodiments, the metal oxide varistor may be a plurality of varistors in parallel; (g) a failure indicator circuit connected to the transient voltage surge suppressor, including at least one relay, one voltage-surge responsive switch and one indicator signalling component.Field of SearchWith threshold detectionWith plural condition sensing For protective system FOR REACTIVE POWER CONTROL Using impedance Surge prevention (e.g., choke coil) In communication systems Thermal (e.g., fusible, bimetallic) With means to introduce or eliminate frequency components In inverter systems In rectifier systems With starting arrangement Including automatic or integral protection means | |
