Electrical fault finding Experience

Fault Finding Experience

Experience of electrical fault finding Marine electrical & electronic systems (both practical & also teaching electro-technical officers &  Cadets in Marine Industry.

Marine permit to Work Procedures.

Fault finding of Single & Three Phase electrical systems used both on Marine environments (Insulated Neutral), and land based Star & Delta based systems.

Experience of Programming Variable Speed Drives, and fault finding cabling supplying the VSD, and from VSD to Induction Motor.

Experience of both teaching and installation of three phase Direct Online Starters (DOL) to Marine Industry students from UK & Internationally.

DOL experience includes, contact inspection and coil replacement of Contactor; fault finding of issues such as ‘Single Phasing’ faults, caused by loose motor connections in terminal box (ships vibration), broken motor Stator, mechanical damage due to to supply cable damage etc.

Experience of  three phase Star-Delta Starter inspection, servicing and fault finding.

Experience of Motor ‘Phasing Out‘ in the case of unidentified Stator connections.

Cable fault finding, though half-split, Input-Output and other methods.

Ships generator / alternator servicing & maintenance checks, including, bearing clearance & wear, Insulation Resistance testing using Insulation Resistance Tester, Stator Continuity checks using  specialist MicroOhmmeter.

Fault finding checks and fault finding on 550 Volt mining equipment starters.

Marine Switchboard maintenance, including ‘racking out’ circuit breakers to check bus bar connections, arc chutes etc. Checking Marine Circuit breakers for trip times using current injection test set.

Auto-Transformer (as used on some Ships Bow-Thrusters) testing and maintenance.

Three Phase Induction Motor stripping down, testing and servicing. Bearing replacement, IR Testing, Continuity Testing, damage inspection, re-assembly & test rig using Clamp Meter, RPM meter & calculations.

Over Current Relay (OCR) testing on test rig. Trip times etc. Electronic, Magnetic & Thermal types.

Delta-Delta Transformer testing.

Delta connected Single Phase Transformer configuration (as used on ships).

Single Phase Transformers, testing and connection (Step up, and step down).

Ships Earth Fault Alarm board testing and maintenance, using Line Tester etc.

Earth Fault testing on an Insulated neutral system.

Supply Synchronisation using simulator, to ensure shore-side and ships generators supplies are in phase before connection. Inductive and capacitive loads.

Radio Communications Fault Finding, including coaxial cable faults, bench testing using Radio Communications Test Set, SWR Meter, Spectrum Analyser, PC software programming of radio equipment, board level repair of two-way radio systems used on land and on ships.

Blue is the colour

According to some research I read recently, most adults prefer the colour blue.

This is why it is a popular colour for logo design and company advertising.

Have a look round and put this to the test. Think Facebook for instance.

Blue is considered to signify calmness and strength, whereas the colour red signifies danger (in nature), and excitement in advertising. Think of Ferrari cars, and Coca Cola. Both use red, and both are promoting fun and excitement.


Test Marketing changes since my marketing degree in the late 90s

When I did a marketing degree in the late 1990s, I remember being taught about researching the market through things like focus groups and surveys of the target market.

This approach is still valid, and gets fast results, however in the internet age there is a cheaper alternative way to find out if your product or service is something that people want.

Set up a carefully written webpage that targets the keywords and phrases that your potential customers might be looking for.

To be continued, when I have more time 🙂
