I want, with great affection and attention, to say that I am very pleased with your presence here on the CADERNO DO TÉCNICO channel. I wish everyone a happy new year. May 2025 be full of success, achievements and lots of learning for everyone, not forgetting, of course, to wish you good health and faith, so that the year is better than the last. Everyone is welcome! We have our content agenda, where we are going to talk a little about the phase sequence indicator PART II. During this year, we had the presentation of this PHASE SEQUENCE INDICATOR, model MFA – 840 A, from the MINIPA brand. On that occasion, we were able to demonstrate in the field the phase loss reading on a 220 volt three-phase network. If I remember correctly, we have a video posted on July 27th of this year, talking and providing guidance on the practical use of this device, the MFA – 840 A, MINIPA phase sequence indicator. Today, we are going to reinforce some important concepts of this instrument, which helps us a lot in identifying the sequence of phases in electrical installations, mainly in the supply of energy for coupling generators in powerhouse lines, which, by law, cannot be subject to only to the supply of energy concessionaires. As has already been said, sometimes, as a professional in the field, you have already had the opportunity to install a network from scratch and, at the end of this service, you have not had the chance to test whether the phases were actually in the correct sequence. The device has an LED phase sequence indicator: GREEN for correct phase. RED for reversed phase. ORANGE for open phase. The probes are identified as follows: YELLOW for R phase (identified as U, A or L1 phase). GREEN for S phase (identified as V, B or L2 phase). RED for T phase (identified as W, C or L3 phase). The tips are convenient for use with an alligator clip, attaching the test tips to terminals with a maximum diameter of 10 mm. Verification method: Correct Phase (Clockwise - CW): Three orange LEDs light up, the green LED lights up, and a flashing beep is emitted. Inverted Phase (Counterclockwise - CCW): Three orange LEDs light up, the red LED lights up, and a continuous beep is emitted. Open Phase (One Phase Only): The orange LED of the open phase is off, the red and green LEDs are off, and it does not emit a beep. The device has an operating voltage of 60 alternating volts up to 600 volts AC, and can be used at operating frequencies from 20 Hz to 400 Hz. Continuous use limit: Maximum 60 minutes at 60V AC. Maximum 4 minutes at 600V AC. The maximum supported voltage is 2000V for 1 minute. The maximum peak voltage is 4000V. I reinforce my wish for a year full of achievements and I hope to count on you for the next year, with new posts and lots of studies. Thank you very much for your company during the year 2024. Your presence here on the channel IS AN HONOR. I'm counting on you to follow us in the next videos. I am your friend and instructor on the CADERNO DO TÉCNICO channel.
