On May 17, 2025, the Mexican Navy’s tall ship ARM Cuauhtémoc collided with the Brooklyn Bridge in New York City while departing the port. The incident occurred around 8:30 PM local time when the vessel reportedly lost propulsion power, possibly due to a mechanical failure, and began drifting in reverse. Its masts struck the underside of the bridge, causing severe damage. As a result of the collision, three masts were sheared off, leading to the deaths of two crew members and injuries to 19 others, including four in critical condition. The ship had 277 people onboard, including naval cadets and crew. It had arrived in New York on May 13 as part of a goodwill training tour and was scheduled to head to Iceland next. Emergency crews quickly responded, and the injured were transported to nearby hospitals. Fortunately, the #Brooklyn #Bridge itself did not suffer major structural damage and was reopened after a temporary closure. An investigation has been launched by both the Mexican Navy and New York authorities to determine the cause of the power loss. Preliminary reports suggest a mechanical failure led to the ship’s loss of control. The ARM Cuauhtémoc is a well-known Mexican Navy training #vessel, built in 1982 in Spain, and has been used for decades to train cadets and serve as a symbol of Mexico’s naval presence in international goodwill missions. https://youtu.be/3cf-_7UZjGo?si=aKD3rcPXJQJj686V #news

Under-Voltage (UV) Coils in Generator Circuit Breakers: Purpose and Common Failures What is a UV Coil? An Under-Voltage (UV) coil is an essential safety component used in circuit breakers, particularly in generator and power distribution systems. Its primary purpose is to automatically trip (open) the circuit breaker when voltage drops below a certain threshold, protecting the system from operating under unsafe or unstable conditions. ✅ Article ➡️ https://www.eto-engineer.com/2025/05/under-voltage-uv-coils-in-generator.html #circuitbreaker #generators #voltage #solenoids #UnderVoltagecoil #UV #generator #coils #ACB #lowvoltage #voltage

#Current transformers (#CTs) are devices used to measure alternating current (#AC) by producing a reduced current proportional to the current in the circuit, which can then be safely monitored and recorded by meters, relays, or protection devices. Key Concepts: • Function: CTs step down high current to a lower, manageable level. • Primary & Secondary #Windings: • Primary winding: Connected in series with the main power circuit. • Secondary #winding: Delivers a scaled-down current, usually 1 A or 5 A, to measuring devices. • Types: • Wound CT: Has its primary winding physically wound on the core. • Bar-type CT: Uses the main conductor as the primary winding. • Window/Through CT: The conductor passes through a core window. Applications: • Power system monitoring • Protection systems (e.g., overcurrent relays) • #Metering and energy audits • #Generator and #transformer monitoring Important Notes: • #CT secondary should never be open while in service—this can result in dangerously high voltages. • #Burden: The load connected to the CT secondary must match its rated burden for accurate readings. ⚠️ Current Transformers (CTs) do not work with #DC because they rely on electromagnetic #induction, which only occurs with changing current (i.e., AC). Why CTs Don’t Work with DC: • CTs operate based on Faraday’s Law, which requires a changing magnetic field to induce voltage in the secondary winding. • DC current creates a constant magnetic field, so no voltage is induced in the secondary winding of a CT. • Trying to use a CT with DC can result in no output or saturation of the CT core, which may damage it or produce false readings. Alternatives for Measuring DC Current: 1. #Shunt Resistors: • A precision #resistor placed in series with the DC circuit. • #Voltage drop across the shunt is measured and used to calculate current via Ohm’s law. 2. #Hall Effect #Sensors: • Measure magnetic fields generated by DC or AC currents. • Can detect steady-state (DC) and dynamic (AC) currents. • Galvanically isolated, making them safe for high-current applications. 3. #Fluxgate Sensors: • Highly accurate for DC measurement. • Often used in high-precision power systems or aerospace applications.

#EUI (Electronic Unit Injector) system How EUI Fuel Injection Works: 1. Fuel Supply (Yellow Line): • #Fuel is supplied under pressure to the injector body from a common rail or supply pump. 2. Electronic Control: • The top-left section shows a solenoid or electronic actuator that controls a valve. • The #ECU (Engine Control Unit) sends an electrical signal to this #solenoid, controlling the timing and duration of injection. 3. #Plunger Mechanism: • A plunger (shown vertically in yellow and red) is driven mechanically by the camshaft. • The plunger pressurizes the fuel within the injector chamber. 4. Fuel #Injection: • When the solenoid valve opens, the high-pressure fuel is released through a nozzle. • The #nozzle atomizes the fuel into the combustion chamber (shown with an orange spray at the bottom). 5. Injection #Timing: • Timing and amount of fuel injected are controlled electronically by the ECU, optimizing combustion and efficiency.
