Power Quality And Harmonic Study

Sachu Technologies responsive that it is essential for its customers to have a continuous, reliable and pure electrical supply for today’s critical industrial and commercial business equipment. The monitoring of electric power helps to identify the important power quality problems such as voltage sags and swells, interruptions, harmonics, and high-frequency noise, consistently seen in industrial and commercial grid applications. Troubleshooting these problems requires accurate measurements and analysis of power quality with monitoring instruments that can effectively locate issues and identify solutions.

External or internal sources can cause voltage sags, surges or unwanted harmonics that can overload, damage or cause mal operation of systems ,Machinery, computers and other sensitive process equipment.For this reason it has developed expert teams proposing an array of Power quality and Harmonic study , Electrical safety Audit and Energy Audit testing, reporting, maintenance and installation services in India Hyderabad, Bangalore,Noida,Chennai,Coimbatore, Kolkata, Visakhapatnam, Nagpur, Delhi, Pune, Mumbai, Ahmedabad, Guwahati, Indore, Surat, Baroda, Kanpur, Kochi, Bhubaneswar, Goa, Lucknow, Vijayawada, Nellore and other cities Such installations include Data Centres, Software companies , IT Parks,Defense Facilities, Health Facilities, Mining Sites, Manufacturing Plants etc.

we can help to diagnose the problem, quantify the magnitude of the problem through analysis and simulation, and recommend methods to solve it.

Harmonic sources

There are many sources of harmonics in industrial power systems, all of which share a common characteristic: a nonlinear voltage-current operating relationship. A nonlinear load has a discontinuous current that does not correspond to the applied voltage waveform. Any device that alters the sinusoidal waveform of the voltage or current is a harmonic producer. This includes such common components as transformers. Transformer inrush currents contain significant levels of low-order harmonics, such as the 2nd, 3rd, 4th, etc. In addition, the transformer magnetizing currents will contain increased levels of the 3rd, 5th, and 7th order harmonics, when the applied voltage is higher than the rated voltage.

Sachu Technologies offering Power Quality Services ideally creates a perfect power supply that is continuously obtainable, has a pure noise-free sinusoidal wave shape, and is always within voltage and frequency.Power Quality Audits Identifies Power Quality issues and further help you address reliability and stability concerns before they actually impact on your facilities performance and more important on bottom line of organization. Power Quality is often defined as the electrical network's or the grid's ability to supply a clean and stable power supply. In other words, power quality ideally creates a perfect power supply that is always available, has a pure noise-free sinusoidal wave shape, and is always within voltage and frequency tolerances. Sachu Technologies aware that it is essential for its customers to have a continuous, reliable and pure electrical supply for today’s critical industrial and commercial business equipment. External or internal sources can cause voltage sags, surges or unwanted harmonics that can overload, damage or cause mal operation of computers and other sensitive process equipment. For this reason it has developed specialist teams offering an array of testing, reporting, maintenance and installation services that are second to none for those of its customers where the continuity and quality of supply are critical. PQ is a measure which defines the ability of a system to support reliable operations of its load. Our Team has the state of art high end 3 phase power quality analyzers to monitor and detect the issues relating to power quality.

     

Sachu Technologies offering Harmonic Study is carried out to check the Harmonic distortion levels in the network and to subsequently identify the Source of Harmonic distortion.
What are harmonics?
The term harmonics commonly refers to a distortion of the normally smooth utility power. Harmonics are actually higher frequency voltages and currents and when added to the utility power, produce a distortion of the normal voltage or current waveform. Usually, harmonic distortion must be present continuously to have an adverse effect on the power system.

 
 

Sachu Technologies offering Electrical Safety Audit to avoid Electrical hazards continue to threaten safety of people and property in the form of shocks, burns, injury, fire and explosion. With electricity having become an indispensable part of our life, electrical risks are to be managed effectively. In process industries, Plants fires due to electrical reasons are very probable, especially in industries that handle flammable chemicals. In service industries such as Software companies, information technology, telecommunications, banking and other commercial establishments, business interruption losses due to electrical hazards (fire in server room, damage of expensive communication equipment, loss of data, fire in cable gallery, etc.) could be substantial.

Sachu Technologies offer Power Factor Study after analyzing consumer power factor in last 12 month billing cycle. The study is carried out at Mains (Upstream) and at various Load Points (Downstream).

Power Factor is ratio of the actual electrical power dissipated by an AC circuit to the product of the r.m.s. values of current and voltage. The difference between the two is caused by reactance in the circuit and represents power that does no useful work.

 
 

Sachu Technologies offering Transients study to identify typically caused by lightning, electrostatic discharges, load switching or faulty wiring.

 
 

Sachu Technologies offering Power Flow study &Load flow studies determine if system voltages remain within specified limits under normal or emergency operating conditions, and whether equipment such as transformers and conductors are overloaded.
