What is Thermography?
Infrared thermography is equipment or method, which detects infrared energy emitted from object, converts it to temperature, and displays image of temperature distribution. To be accurate, the equipment and the method should be called differently, the equipment to be called as infrared thermograph and the method to be called as infrared thermography.
Advantage of thermography
It is non-contact – uses remote sensing.
It keeps user out of danger while scanning live electrical components
Targets at very high position can also be detected
Does not affect the target
No SHUT DOWN is required.
Power Quality Test
To achieve the objective of this study, the power quality shall be assessed based on following parameters:
Harmonics – sinusoidal voltages or currents having frequencies that are integer multiples of the frequency at which the supply system is designed to operate
Phase-phase/Neutral RMS voltage variations.
Ground – Neutral RMS voltage variations.
Load RMS current variations
Power Factor – Improvement in power factor
Earthing System Test
In electricity supply systems, an earthing system or grounding system is circuitry which connects parts of the electric circuit with the ground, thus defining the electric potential of the conductors relative to the Earth’s conductive surface. The choice of earthing system can affect the safety and electromagnetic compatibility of the power supply. In particular, it affects the magnitude and distribution of short circuit currents through the system, and the effects it creates on equipment and people in the proximity of the circuit. If a fault within an electrical device connects a live supply conductor to an exposed conductive surface, anyone touching it while electrically connected to the earth will complete a circuit back to the earthed supply conductor and receive an electric shock

Insulation resistance test
An insulation resistance (IR) test measures the total resistance between any two points separated by electrical insulation. The test, therefore, determines how effective the dielectric (insulation) is in resisting the flow of electrical current. Such tests are useful for checking the quality of insulation, not only when a product is first manufactured but also over time as the product is used.
Loop Impedance test
An earth loop impedance test is conducted to make sure that, if a fault occurs in an electrical circuit, the fault current will strong be enough to set off the circuit protection. If a fault current is left undetected, circuits can overheat and catch on fire.
Electricity takes the path of least resistance to the ground. Electrical wiring systems in buildings are often connected to the ground. This is referred to as an earth return circuit. The grounding wire is there for electrical current to pass through when a short circuit happens.
