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 & 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)
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 & Relays)
Advantages of thermography
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
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.

Economic Value:
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 & 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 & 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).
