Thermal Audit for Electrical

We are engaged in providing our clients Electrical Thermography or Thermal Audit By Qualified Professionals. An infrared electrical inspection can minimize injury, liability, damage, catastrophic failures and downtime of the organization,

Many conventional electrical problems have unconventional answers, which are not revealed in routine inspection. Small faults may be negligible but could create lasting damaging effects to life & property in the long run.In electrical systems component's age, fatigue, oxidation, wear & tear, loose connections , poor installation can increase resistance & heat .

Infrared cameras catch this heat. This is why an Infrared electrical inspection is the best way to detect early electrical failures, because most electrical things tend to get hot before they fail) IR Inspection mainly involves scanning, image taking and image analysis and among them analysis part is most important for correct diagnosis of problems.

Thermal Audit can detect many problems in many electrical systems such as following :

  • Switchgear in organization and substations
  • Transformers
  • Power transmission lines
  • Determining which energy-saving solutions are considerable
  • Distribution panels, circuit breakers and conductors
  • Computer and low voltage systems
  • Machine control Panels
  • PLCs (Valves & Relays)

Advantages of Thermal Audit:

  • Infrared Thermal imaging can help you detect problems like inductive heating, hot bus bar ,overloaded circuit & many undesirable electrical situations
  • It can be used to measure or observe in areas inaccessible or hazardous for other methods
  • It is a non-destructive test & contact free method
  • Thermography inspect electrical objects in dark areas
  • Distribution panels, circuit breakers and conductors
  • An Infrared inspection can immediately detect an overheated wire in the mesh of wires and terminals, which is impossible to see with naked eyes.
  • An infrared electrical inspection can minimize injury, liability, damage, catastrophic failures and downtime of the organization An effective preventative maintenance strategy must include an infrared scan.

Electrical equipment’s can suffer from numerous faults which will show and increase in temperature:

  • Corroded or loose connections
  • Imbalanced Loads
  • Using underrated equipment or overloading equipment
  • Insulation Damage
  • Incorrect voltage
  • Blocked or poorly ventilated equipment
  • Deterioration due to age
  • Exceeding the recommended temperature rating

The electrical equipment’s which are surveyed would include:

  • Motors and motor control panels
  • Control equipment
  • Cable runs
  • Substations
  • Transformers
  • Circuit operating devices
  • Thyristor banks
  • Switches, fuses and circuit breakers
  • Distribution boards

Scope of work:

We shall cover the following under scope of work for Thermal audit:
  • We will carry out the Thermography under full load condition Online.
  • We shall remove the doors & covers of the Main DB's LT Panels & Sub-distribution panels.
  • The real Image & Thermal Image of each switch-gear will be recorded for any temperature variation.
  • If there is any abnormal temperature rise, then the parameters like rating of switchgear & cables & cooling system/ventilation will be evaluated
  • The peak & RMS current flowing through the conductor/switchgear.
  • If any loose connections/corrosion of contacts is found, the same shall be mentioned in the report for further corrective action.
  • This one activity is treated as one electrical point.
  • The time required for conducting this process is @30-45 min depending on the location & accessibility.
  • We shall carry out this process for LT room, DG room & DG working on DG mode, Change-over panel, Main incoming Transformer & its Switch-gears (is carried out at evenings after sunset). Floor-wise distribution panel (If required).
