STERLING Model ANTS-1 Artifical Neutral Kit (CSA Approved)

The artificial neutral is designed for use on poly-phase ungrounded (Delta) systems. It is powered from the AC line or internal rechargeable battery. It provides an intermittent grounded neutral enabling the detection of fault current on ungrounded networks.

Because the flow of the current is interrupted at periodic intervals it is distinguishable from the load current. Two speeds (fast/slow) of neutral application are provided so that analogue or digital instruments can be used for detection. Three red lights located under the phase inputs indicate the presence or absence of phase voltages. Battery state light above the line input connector shows charge (red) or fully charged battery (green). Adjacent to the speed selector is the relay status light that is green when the relay is operating. In addition there is also a buzzer activated by the relay operation.
