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.
How to properly size a motor circuit breaker? This article will tackle about the sizing of Inverse Time Circuit Breaker with regards to National Electrical Code (NEC). I have learned this not just in school, but also in review center for our national board exam. It's one of the essential topics you should know for future use especially in the design field. What is Circuit Breaker? Circuit Breaker is an over current protective device that can manually switch on/off and automatically trip when a short circuit fault occurs. Why do we need to size a circuit breaker? Circuit Breaker rating is sized according to its load/s. Thus, undersized circuit can always give false alarm to operation. While oversized can lead to equipment breakdown or
