All About Emergency Generator on Ships

The role of the Emergency generator on the ship is to provide backup power for the emergency loads in case the main generator fails or blackout condition. It is part of the larger emergency machinery and systems installed on large ships related to the engine room. Located outside the machinery space these are much smaller […]

How To Overhaul Electrical Motors On Ship And Industries ?

Everything that is ever built or created has a self life; and it takes proper care and maintenance to prolong their life span. An electrical motor with its five major parts; rotor, stator, winding, terminal box and bearings require overhaul from time to time to ensure safe operation. If not; the first thing which happens […]

How To Successfully Parallel Generators ? | Step By Step

When two or more generators with same frequency, voltage and phase difference are connected to the bus-bar; such that it increase their overall capacity, ease of maintenance, and active load management. Then they are called to be connected in parallel; and the method used is called paralleling. While the process used in this method to […]
