3 Pole Trinity PFC1729 Power Factor Correction Relay

The relay is meant for flush mounting in a panel for connection to the electrical system.The relay is the ‘intelligence' which controls the automatic system for correction of the power factor. It senses the power factor by taking the ratio of the KW and the true rms KVA of the system, for any phase to neutral or phase to phase connections of the three phase electrical system. This means that phase to neutral or phase to phase are connected to the meter as voltage inputs and current of the same phase or different phase as current input. For correct operation of the relay, however there are some minimum requirements should be met. Unless the various points in the system which are mentioned below are correctly setup, proper operation of the relay cannot be expected. Features All readings are true RMS measurements Site selectable 1A or 5A CT secondary Automatic power factor control through system PF. Programmable target PF setting (from 0.800 to 1.000 LAG or LEAD) Programmable Time delay for step switching (Normal: 40-300, Fast: 1-10 Sec) Stage wise LED indication Auto/Manual mode selection through programming mode Normal/Fast switching control action is site programmable Alarm and tripping indication for over/under compensation and over/under voltage respectively Installation selection for phase to phase(L-L) or phase to neutral(L-N) input is site selectable Control action with/without capacitor CT is site selectable Switch ON/OFF banks manually in manual mode only
