AVR, Rectifiers, and Windings Inspection
During a generator inspection, the Automatic Voltage Regulator (AVR) is checked for proper operation and stable #voltage control. Electrical connections are inspected for tightness, overheating, and signs of damage. The #AVR settings and feedback signals are verified to ensure correct #excitation control.
The rectifier assembly is inspected for damaged or overheated diodes, loose connections, discoloration, and proper heat sink condition. Diodes can be tested with a multimeter to confirm they are operating correctly, as a faulty #rectifier may cause unstable voltage or reduced generator output.
The #generator windings are visually inspected for contamination, moisture, insulation damage, loose bindings, and signs of #overheating. #Insulationresistance is measured with a #megohmmeter to assess the condition of the winding insulation. Any unusual discoloration, burning smell, or evidence of partial discharge should be investigated, as these may indicate insulation deterioration or #winding failure.

| 3 |  For an industrial proximity sensor on a ship, the basic test is:
1. Check supply voltage at the sensor — commonly 10–30 VDC (check the sensor label).
2. Check output with a multimeter while bringing a metal target close.
• PNP: output should switch approximately 0 V → +24 V.
• NPN: output should switch approximately +24 V → 0 V.
3. If it has an #LED, it should change state when the target reaches the sensing distance.
4. Check the sensing distance by moving the target slowly toward the sensor. It should switch reliably and repeatedly.
5. If there is no switching, check the sensor face for dirt/damage, wiring, supply voltage, and finally test the sensor disconnected from the #PLC.
For a 2-wire #proximitysensor, the testing method is different because the #sensor is usually connected in series with the load.
If you send me a photo/model number and #wiring, I can tell you exactly where to put the #multimeter probes and what #voltage you should get. | 432 |

| 8 |  +3A #pressuretransmitter is an electronic device that measures the pressure of a liquid, gas, or steam and converts it into a standard electrical signal that can be read by a #PLC, controller, or automation system. The most common output signal is 4–20 mA, although 0–10 V and digital communication protocols such as #HART, #Modbus, or #CAN are also widely used.
Inside the transmitter is a sensing element that deforms when pressure is applied. The built-in #electronics convert this deformation into an electrical signal proportional to the measured pressure. For example, if the #transmitter has a measuring range of 0–10 bar, it will output 4 mA at 0 bar, approximately 12 mA at 5 bar, and 20 mA at 10 bar.
On ships, #pressuretransmitters are commonly used to monitor lubricating oil, fuel oil, cooling water, compressed air, hydraulic systems, ballast lines, and fire main #pressure. The measured values are displayed on operator panels, used by automation systems for process control, and provide alarms and equipment protection. | 623 |

| 11 |  The Fluke 381 is a professional True-RMS AC/DC #clampmeter designed for electrical #troubleshooting. Its main feature is the removable wireless display, which allows you to take measurements while viewing the readings from a safe distance.
It can measure AC/DC current up to 999.9 A, AC/DC voltage up to 1000 V, resistance up to 60 kΩ, and frequency up to 500 Hz. With the included #iFlex flexible current probe, it can measure AC current up to 2500 A. It also provides Inrush Current, Min/Max/Avg measurements, continuity, backlight and a low-pass filter for measurements on noisy electrical systems.
The #Fluke 381 is rated #CAT III 1000 V / CAT IV 600 V. For an #ETO, it is especially useful for checking generators, motors, switchboards, feeders and high-current circuits where the remote display improves safety. | 1 941 |

| 20 |  🤔 Why are almost all circuit boards green? 🟢
The short answer is: they don’t have to be green, but green became the industry standard because it offers the best balance of cost, manufacturing quality, and ease of inspection.
Here are the main reasons:
- The green layer is the #solder mask. The #fiberglass board underneath (usually FR-4) is naturally yellowish or light brown. The green coating protects the #copper traces from corrosion, prevents solder bridges, and provides electrical insulation.
- #Green provides the best contrast. Copper traces, white silkscreen markings, and solder joints are easy for technicians and automated optical inspection (#AOI) systems to see on a green background. This makes defects easier to detect.
- Manufacturing history. Green solder mask was one of the first formulations to become highly reliable and inexpensive. Since millions of #PCBs have been produced this way for decades, it remains the most economical choice.
- Good optical properties. Green reflects light in a way that reduces eye strain during manual inspection compared with some darker colors.
Why are some PCBs other colors?
Today, manufacturers can produce almost any color:
- Black – Premium appearance, but traces and defects are harder to inspect.
- Blue – Common in consumer electronics and prototypes.
- Red – Popular for development boards.
- White – Used in #LED lighting because it reflects light well, but shows dirt and flux residue easily.
- Yellow, purple, matte black, etc. – Mostly chosen for branding or aesthetics.
The color does not affect the electrical performance of the #PCB. The #circuit works the same whether the board is green, blue, black, or red. The differences are mainly in manufacturing, inspection, cost, and appearance.
For marine #electronics, industrial control systems, and power electronics, you’ll still find that green is by far the most common color because it is proven, economical, and easy to inspect during #maintenance. | 486 |
