Phase Sequence Meters
-
Phase sequence meter is used for detecting the sequence of the supply in three-phase electric circuits. Since the direction of rotation of three phase electric motors can be changed by changing the phase sequence of supply. And also the correct operation of measuring instruments like 3 phase energy meter and automatic control of devices also depend on the phase sequence. Different types of phase sequence testers are available in today’s market like contact or non contact, static or rotating, etc., in a wide range of voltage or power ratings.

Phase Monitors
-
NAI''s AC- and DC-powered Phase Monitors are used to protect three-phase loads from damage due to phase reversals or phase absence. Contacts may be used to disconnect the load or to operate alarm circuits or both. Upon application of power, the output relay energizes if all phases are connected and the phase sequence is ABC. If any phase becomes disconnected or if the phase rotation is abnormal, the relay immediately de-energizes. These monitors are specifically designed for rugged defense and industrial applications.
