DEIF FAS-115DG: Multi-Function Sensor for Power Generation

Description:

The DEIFFAS-115DG(P/N:100032106.250)is a multi-function frequency and current sensor designed for generator monitoring and protection applications.This compact device provides essential electrical measurements for power management systems in marine,industrial,and standby power applications.

Application Scenarios:

On an offshore supply vessel,the main generator protection system suddenly triggered a false under-frequency alarm during rough weather operations,causing critical equipment to switch to backup power unnecessarily.The vessel’s engineer identified the DEIFFAS-115DGsensor as the source of the inaccurate frequency readings.This sensor continuously monitors generator output to prevent damage from abnormal operating conditions.Replacing the faultyFAS-115DGunit restored accurate frequency measurement,eliminated nuisance trips,and ensured reliable power availability for navigation and dynamic positioning systems during challenging sea conditions.

Technical Principles and Innovative Values:

Innovation Point 1:Dual-Function Measurement Capability.TheFAS-115DGcombines accurate frequency measurement and current monitoring in a single compact unit,eliminating the need for separate sensors.This integrated approach reduces panel space requirements and simplifies wiring while providing comprehensive generator monitoring for under/over frequency and under/over current protection.

Innovation Point 2:Advanced Signal Processing.The sensor employs sophisticated digital signal processing algorithms that filter out electrical noise and transient disturbances,ensuring stable and accurate measurements even in electrically noisy marine or industrial environments.This results in reliable protection without nuisance tripping during normal operational variations.

Application Cases and Industry Value:

A hospital’s backup power system upgrade incorporated DEIFFAS-115DGsensors to monitor two new 1000kVA generators.During a city-wide power outage,the sensors accurately detected grid failure and initiated automatic generator startup.TheFAS-115DGunits continuously monitored frequency stability during load acceptance,preventing potential damage when large HVAC motors started simultaneously.The system maintained critical medical equipment operation throughout the 8-hour outage,demonstrating the sensor’s vital role in reliable emergency power availability.

Installation,Maintenance,and Full-Cycle Support:

Installation&Maintenance:TheFAS-115DGrequires proper DIN rail mounting in a controlled environment.Ensure correct voltage and current transformer connections following DEIF wiring diagrams.Regular verification of measurement accuracy against calibrated test equipment is recommended during scheduled maintenance.Check relay operation and contact cleanliness annually.
