Power Quality is a concept of powering & grounding electronic equipment in a manner which is suitable to its operation & compatible with premise wiring system & other connected equipment.

1. Power Quality Analysis
Power Quality is a concept of powering & grounding electronic
equipment in a manner which is suitable to its operation &
compatible with premise wiring system & other connected
equipment.
We at Network Techlab conduct PQA to our customer which involve a visual inspection
of the site understudy installation of power analyzers at various locations to monitor power
parameters, collect data interpret the same.
Also as the performance of the critical equipment depends on other non-electrical
parameters, magnetic field strength & static charges are also measured.
Power Analysis Objectives -
Protection from dangerous of power outrages or power swings.
Prevention of any kind of losses or interruptions in business.
To suggest & recommend necessary modifications, repairs, addition to the system.
To Provide a large data base of recorded disturbance to identify the types of power
deviations that exists which can effect the performance & safety of linear & non linear load.
What is Power Quality?
Equipment - Fluke 435 Power Quality Analyzers

4. Thermal Image Normal Image
Thermography
Temperature is the physical property that quantitatively expresses the common notations of hot & cold. Every
object emits energy in electromagnetic spectrum. The wavelength of the energy differs depend on materials. As
shown below; if the wavelength is in the range between 400 nm to 720 nm i.e. visible range, then the body would
be visible. If the energy emitted is having wavelength beyond 720 nm, then it would be invisible. This infrared
energy can be captured using Thermal Imager.
Thermography is the non-contact analysis & mapping of thermal patterns of an object. It’s known that all objects
emit infrared radiation based on their temperature. Thermal imagers detect this infrared radiation & according to
the black body radiation law, thermography makes it possible to see one’s environment with OR without visible
illumination. As such Thermography is used to monitor & analyze the performance of electrical equipments & if
done properly can help prevent fire hazards/failures.
