Electrical Engineering, especially for BEMS

 

General Power Distribution (Inside Buildings)

  • Main Distribution Board (MDB) – central point for electrical distribution.

  • Sub Main Distribution Board (SMDB) – smaller boards branching from MDB.

  • Final Distribution Board (FDB) – supplies end-user loads (lighting, sockets).

  • Circuit Breakers (MCB, MCCB, ACB, RCD/RCBO) – protection devices.

  • Busbars – metal strips that distribute high current within switchgear.

  • Transformers (LV/MV step-down) – reduce incoming voltage for building use.

  • Diesel Generator (DG Set) – backup power for critical loads.

  • UPS (Uninterruptible Power Supply) – backup for IT, servers, and security systems.

  • Automatic Transfer Switch (ATS) – shifts power from mains to generator.

  • Earthing & Grounding System – safety against faults.

  • Lightning Protection System (LPS) – roof-mounted lightning arrestors.


💡 Lighting & Power Systems

  • General lighting system – offices, lounges, corridors.

  • Emergency lighting / Exit signs – powered by battery or central UPS.

  • Motion sensors / Occupancy sensors – for energy saving.

  • Lighting Control Panels (LCP) – centralized control of building lights.

  • Socket outlets – for passengers, offices, kiosks.

  • High mast / floodlighting (apron visible from terminal glass) – inside building perimeter.


🏢 BEMS (Building Energy Management Systems)

  • Building Automation System (BAS) – centralized monitoring of HVAC, lighting, and energy.

  • HVAC Control – chillers, AHUs (Air Handling Units), VAVs (Variable Air Volume).

  • Lighting control integration – schedule & dimming.

  • Energy metering & monitoring – smart meters for each zone.

  • SCADA integration – real-time monitoring and alarms.

  • Sensors – temperature, CO₂, occupancy, lux level.

  • Demand load management – peak shaving, energy optimization.

  • Remote dashboards & reporting – web/mobile monitoring.


🔔 Low-Current & Safety Systems (Inside Terminal)

  • Fire Alarm & Detection System (FA&DS) – smoke/heat detectors, fire panels.

  • Public Address & Voice Evacuation System (PAVA) – announcements.

  • Access Control System (ACS) – restricted areas, card readers.

  • Closed Circuit Television (CCTV) – security cameras.

  • Baggage Handling System (BHS) Power Supply – conveyors, scanners.

  • Passenger Boarding Bridge (PBB) Power Supply – at gates.

  • Flight Information Display System (FIDS) – screens and control rooms.

  • Data Centers & IT Rooms – critical server power with UPS and cooling.


🛠️ Installation & Testing Terms

  • Cable trays & trunking – supports for routing cables.

  • Conduits (PVC, GI) – protection for electrical wiring.

  • Cable pulling & termination – installing cables into DBs and panels.

  • Glanding & crimping – connecting and securing cables.

  • Junction boxes – connection points for wiring.

  • Megger Test – insulation resistance testing.

  • Continuity Test – ensuring connections are complete.

  • Functional Testing & Commissioning – verifying systems before handover.

  • Method of Statement (MOS) – step-by-step procedure for installations.

  • Inspection & Test Plan (ITP) – quality checks during installation.

  • Permit to Work (PTW) – safety authorization before work.
