Thermography Services

We are engaged in providing our clients Electrical Thermography 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 and property in the long run.

In electrical systems component’s age, fatigue, oxidation, wear and tear, loose connections , poor installation can increase resistance and 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)

Thermography can detect problems in many electrical system such as

Switchgear in organization and substations
Transformers
Power transmission lines
Distribution panels, circuit breakers and conductors
Computer and low voltage systems
Machine control Panels
PLCs (Valves and Relays)

Advantages of thermography

Infrared Thermal imaging can help you detect problems like inductive heating, hot bus bar ,overloaded circuit and 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 and contact free method
Thermography inspect electrical objects in dark areas
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.

Thermo- graphic Survey - Electrical Systems

Thermal imaging is an extremely useful tool for electrical fault finding. It requires no contact being made with the components which means that the components can be checked in a live state with little danger to the user, there is no effect on the components or interruption in any processes the electrical system may be controlling.

Electrical equipment can suffer from numerous faults which will show an 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

A typical survey of electrical equipment might include:

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

IR Inspection:

IR Inspection mainly involves scanning, image taking and image analysis and among them analysis part is most important for correct diagnosis of problems.

Failure of equipment, machine in electrical or any system may result in loss of production, injury, fire or other damages to property etc., all resulting financial loss. IR Inspection identifies fault sites in advance and suggests for corrective actions based on fault severity. IR Thermography removes unnecessary preventive maintenance and typically in ordinary circumstances 30 to 40 % of the maintenance costs can be saved.

Advantages –

• Finds problem before it finds you!
• Less expensive;
• Reduce maintenance cost;
• Extend asset life;
• Reduce inventory base;
• Increase product quality and consistency.

Scope of work for Thermography: -

We shall cover the following under scope of work for Thermography:

• We will carry out the Thermography under full load condition Online.
• We shall remove the doors and covers of the Main DB’s LT Panels and Sub-distribution panels.
• The real Image and 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 and cables and cooling system/ventilation will be evaluated
• The peak and 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 and accessibility.
• We shall carry out this process for LT room, DG room and DG working on DG mode, Change-over panel, Main incoming Transformer and its Switch-gears (is carried out at evenings after sunset). Floor-wise distribution panel (If required).
