The designed and constructed device detects and automatically corrects phase reversal with the use of electrical circuit involving electromagnetic contactor incorporating timer relay at the heart of the controller. In addition, it also incorporates under/over-voltage and phase failure protection. This is to ensure that connected loads operate within their manufacturers’ specified voltage limits and also are protected against any damage that could result in the event of a phase loss. | Design and development of an automatic three-phase sequence reversal detection and correction for industrial equipment structure
