Part of being in Maintenance or Engineering Department in plant is the Corrective Actions where equipment or parameters are having issues or fault. To be an expert in solving problems or troubleshooting requires years of experience in plant. One of the hardest parts of corrective maintenance is dealing with aged systems. “Abandoned” electrical panels, system with obsolete models, etc. Untagged 6-phase motor could be one of them. In case of emergency that we need to use a motor with untagged leads, what would you do? This article will show you how to identify untagged 6-leads out, 3-phase motor. This is one of the topics that I thought to my class when I worked as a part-time teacher. Before you do the steps, make
Reliability is one of the most important aspects we should be focused on especially when it comes to Plant Maintenance. Frequent shutdowns in plant could be caused by poor maintenance management and lack of advance tools to keep the system running. For a plant working 24/7, most of the running equipments should be treated critically and monitored regularly. However, Redundant Systems are used to save the plant from shutdowns if failure occurs. Aside from back-up power we should always thought of back-up systems that will manually or automatically take over the operations in the event of fault or alarm. In this article, I will share with you the redundant systems that I have encountered by working in Maintenance Department and Engineering Design.
As a technician in plant, I learned that Maintenance and Reliability are the two things we should focus on. In most cases, plant personnels are more focused on Corrective actions rather than Preventive and Predictive approach. In this article, I'm going to share with some of the things I've learned from my previous job in plant. However, we will focus more on Vibration, Lubrication, Energy and Intercoolers.

It is thus appropriate, for that, to define the main types of maintenance met: Preventive Maintenance Stops are envisaged systematically, at
