Lead-Acid Batteries Care and Maintenance on Ships

Care and Maintenance of Lead Acid Marine Batteries on Ships Lead-Acid Batteries on ships provide an important function. In the event of a ‘black out’, or loss of generator power, they allow the ships important systems to continue to operate, until backup generators ‘kick in’, or repair can take place. Important systems include communications, such […]

Marine Radio Equipment Installation

Marine Radio Equipment Installation on Ships Having talked with many current, and retired Electro Technical Officers (ETO), it is apparent that radio communications  is considred by some, a ‘Black Art’. The main two frequency bands that you will come across on a Marine vessel are HF & VHF. HF is short for High Frequency, and […]

What happens when you get a three phase Induction Motor wet

Flooded or Wet Induction Motors First of all, try not to! When designing a marine of industrial installation, you need to consider the IP, or ingress protection rating of your Induction motor. By choosing a motor with a high enough IP rating, it is possible that when you submerge your Induction Motor, nothing will happen. […]

Single Phasing In Three Phase Marine Induction Motors

Single Phasing Faults In Marine & Land Induction Motors Single phasing is the term used when one of the three stator windings in an induction motor is not ‘energised’. Three reasons for this happening in a Marine (& Land) environment are:- Mechanical vibration – causing the terminal nuts to become loose, and therefore disconnecting a […]

Industrial & Marine Induction Motor Servicing Tips

Marine Induction Motor Servicing Tips Safety & Isolation of supply when marine induction motor servicing. Taking a casual approach to marine induction motor servicing & electricity can prove fatal. This is especially true when we are talking about three-phase motors, as they operate in the UK & EU at 400 Volts Alternating Current (400 VAC). […]

Tips for Servicing Marine & Land Based Induction Motors

Safety & Isolation of supply of induction motors. First tip, taking a casual approach to electricity can prove fatal. This is especially true when we are talking about three-phase motors, as they operate in the UK & EU at 400 Volts Alternating Current (400 VAC). Marine installations typically operate at an even higher 440 Volt […]

Phasing Out – Three Phase Induction Motors – on ships

Phasing out a Three Phase Induction motor, onboard ships (or on land)  is the process of identifying both ends of each of the three stator coils (3 phase motor). 'Phasing Out' pic.twitter.com/RMLqyjbs0u — Craig Miles (@acraigmiles) October 17, 2016
