4 Port Devices
Four port devices can be realized by joining two 3 port devices via the appropriate ports. As system performance requirements become more demanding, new design approaches must be adopted. These include Faraday rotation devices and phase shift circulators. The bandwidth and isolation limitations of 3 port devices are overcome through a distributed architecture that enables more ferrite material to be incorporated into the transmission path, thereby achieving an increase in the biasing magnetic field. Phase shift circulators can be designed to handle higher RF power than 3-port devices.

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.
