Importance of Transformer Efficiency - Effect of Loading
Importance of Transformer Efficiency- A distribution transformer is a part of every electrical power network at user end. If a facility is being supplied on HT from the utility, transformer and its losses comes under user’s responsibility. Like any…
K-Factor for Transformer
What is the K-factor? K-factor for an electrical network primarily relates to non-linear loads and is defined as a number representing the effect of harmonics on the heating of the transformer. For calculating the K-factor all the harmonics up to a…
Tackling Electricity Theft in India
Indian government has announced an ambitious plan of setting up hundreds of smart cities across the country. However, no city can be called a smart city unless government can provide uninterrupted power. One of the major reasons behind long power…
Smart Cities and Smart Grid
The Indian government has announced an ambitious plan of setting up hundreds of smart cities across the country. A critical and important part of a smart city is to have an efficient electrical infrastructure, often termed as a smart grid. Little…
Tracking your Energy Management KPI
I recently met an old friend who is currently managing operations at one of the hospitals of a large healthcare company. One of his KPIs is to reduce his energy bill on a month-on-month basis. He told me that he knows how to do this, but he does not…
Energy Data and Production Schedule
Smart Energy Meters are getting smarter. The smart meters are providing energy data that is being used not only to monitor and analyze energy consumption but also to draw insights about other business areas. For example, an MD of a large…
Why Energy Intelligence Software
The cost of electricity has been increasing rapidly – both because of increased prices and increased demand. Since electricity spends is one of the major operating costs for both commercial and industrial consumers, reducing and keeping a tight…
Current and Voltage Unbalance- causes and counter measures
What is unbalance? Any deviation in voltage and current waveform from perfect sinusoidal, in terms of magnitude or phase shift is termed as unbalance. In ideal conditions i.e. with only linear loads connected to the system, the phases of power…
Demystifying Power Factor Compensation
What is power factor? Power Factor (P.F.) can be viewed as the percentage of total apparent power that is converted into real or useful power. Mathematically, we can say that the active power (P) can be represented as: It is also seen as the…
