Apart from its well established product range selec is also rapidly growing in the area of digital panel meters plcs. Analog monitoring relay phase failure and sequence 3x 160 to 690v ac 50 to 60 hz 1 changeover contact screw terminal product function phase monitoring relay measuring circuit. Phase loss cannot be detected on the load side because. How to wire a phase failure device.

If a phase failure occurs on l1 the control relay cr c ontacts change state. Negative sequence relay definition. The relay will not operate if the input voltage drops below 70 of the minimum input value because l1 and l2 are also used to provide power. A relay which protects the electrical system from negative sequence component is called a negative sequence relay or unbalance phase relay.
