CT Scanner Power Supply Issues

By MedBazaar Technical Team · Troubleshooting Guide

مسئلہ / Problem

CT scanner power on nahi hota, randomly shutdown hota hai ya power-related errors aate hain.

CT Power Requirements

  • Typical CT: 3-phase power, 380-415V
  • Current: 30-60A per phase (model dependent)
  • Power quality critical: voltage fluctuation < ±10%
  • Dedicated circuit required — shared power nahi

    • ممکنہ وجوہات / Possible Causes

  • Mains power quality poor
  • UPS/conditioner failure
  • Internal PSU fault
  • Circuit breaker tripped
  • Grounding issue

    • تشخیص / Diagnosis Steps

  • Main circuit breaker check karein — tripped to nahi
  • UPS status check karein
  • Input voltage measure karein (3-phase voltmeter)
  • Error code note karein

    • حل / Fix (User/Facility)

  • Circuit breaker reset karein (agar tripped)
  • UPS bypass mode try karein
  • Power company ko notify karein agar supply issue
  • Voltage log check karein agar available

    • Engineer Required

  • Internal PSU diagnosis aur replacement
  • Grounding system check
  • Power quality analysis
  • Internal circuit breaker replacement

    • Pakistan-Specific

    Load shedding CT scanner ke liye bahut harmful hai. Industrial UPS (min 60KVA) mandatory hai CT ke liye. Generator auto-transfer switch bhi install hona chahiye.
