Resort Hotel Energy Saving with Encon Optimization. Corporate Building fixes UPS and Elevator problem. Intelligent Building eliminates UPS and Elevator failure How to troubleshoot the extraordinary equipment failure, electrical fire and occupants' safety issue in a building?
Read this case study how building harmonic filter fixes light flicker & UPS tripping with grid voltage fluctuation. How harmonic causes electronic card failure and creates trouble with elevator operation. The quality of the incoming power supply from the utility grid carries crucial performance parameters for the building equipment. Why UPS fails to mitigate incoming voltage fluctuation. Solar Power Inverter with Harmonic Filter. Solar Power Inverter An automobile industry was facing high incident of harmonic failure in SCADA, motor drive & electrical equipment after installing 1MW solar power inverter.
The rated capacity of 1.0MW DC solar power is evacuated through 16Nos, 50kW, 3Phase, 415Volts, 50Hz solar string inverter which itself got affected with the harmonic problem. While designing the solar string inverter a 20% power loss is considered by the solar panel manufacturer for conversion from DC solar panel power to AC power delivered in the 3Ph, 415V, 50Hz electrical power grid. Every day during the peak solar power generation when the sun is at the top of the sky, randomly one inverter trips and remains switched off for several hours. Harmonic Filter Solution. Harmonic Filter Solution Harmonic Filter solution is an engineer's approach to increasing 3P, Power, Productivity and Profitability.
No stoppage. Rolling Mill improves with Harmonic Filter. This Rolling Mill derived multitude betterments; solved waviness in sheet metal got rid of dc drive failures and achieved energy saving by installing harmonic filter.
Waviness relates to widely placed variations in the surface texture a key quality parameter of the final sheet metal product. Mill operators reported reduced humming noise with the harmonic filtering, which was due to high-frequency harmonic currents. Harmonic reduction optimized rolling mill operation and facilitated the elimination of the coil defect, which used to cause waviness during the milling process more so with lower gauge copper sheets. Harmonic Filter slashes energy cost and equipment footprint in rolling mill. Harmonic Filter Manufacturer An Extraordinary Troubleshooter. Power Quality Analysis mitigates SCADA and HMI Failure. Power Quality Analysis in a tyre conglomerate revealed the root cause of repetitive electronic card failures in SCADA, HMI, Hard Disk and AC/DC Drives and frequent unwanted tripping in its process due to voltage fluctuation.
The supervisory control and data acquisition system, which is a combination of software and PLC/Computer hardware, malfunctions in sending correct batch data from HMI to process computer missing out a few process data, each day. The LED fitting driver fails due to triplen harmonics which in-addition cause a neutral current in the lighting transformer feeder. The Curing section is most sensitive in the tyre manufacturing process which used to trip frequently on voltage fluctuation.
During monsoon, there used to be persistent tripping with chronic grid voltage surges. The plant management planned to upgrade the 33kV grid incomer to 132kV for solving the tripping problem. Electrical Failure Analysis. An Electrical Arc Furnace was facing Electrical Failure from power system harmonic resonance.
Failure analysis simulation & electrical design for prevention. Abstract: An Electrical Arc Furnace near a hyperactive railway traction line was facing electrical failure from an unusual power quality harmonic distortion problem. The Gigantic 22kA copper bus bar used to overheat visibly red-hot, vibrate audibly loud loosening nuts and bolts and wear out affected plates. In-addition, it frequently encountered other harmonic problems like bulging and blasting of detuned capacitor, motor overheating and failures, HPMV lighting ballast failures, 33kv fuse blowing and overheating of the Electric Arc Furnace transformer. Drive Failure happens with High Harmonics. Industrial Drive Failure with power electronic-based AC VSD and DC Drive or computer hard disk drive, results in a power system with crammed harmonic energy sources.
VSD and DC drives are NLL and harmonic generators. The solution is between costly derating or efficient harmonic solution as applied in this case study. Increase Productivity through Harmonic Solution. Abstract- Harmonic solution is an engineer's approach to total productive maintenance (TPM) to Increase Productivity.
No stoppage. No breakdown. No quality rejection. A 3500 TCD sugar milling unit was operating at 3000 TCD due to frequent drive stalling problem with dc mill motor. To increase productivity and sugar recovery, it installed a 2000A passive tuned harmonic filter in 2010, at a 3MW 415V Turbine Generator (TG). VFD Harmonic caused drive failure and Arc Flash. When VFD drive is sizeable or many, the excessive heat and power surge due to VFD harmonic generated high waveform distortion causes drive failure and unwanted tripping.
Read this case study how harmonic filter for VFD solved the problem including an arc flash incident whose root cause detailed in another webpage "harmonic filter powerful with super tuned specification". VFD Harmonic forced a power plant to shutdown due to power quality failure. Green Building Design. Green Building Design has become the energy conservation norm since Global Warming opened a vast & uncertain expanse at the dusk of rapid industrialization.
That's increasingly threatening us like never before. Unfortunately, the major pie of its cause is related to the energy that we can't live without. Looking at the inevitable our engineering design practices are bound to take a material shift. Power Quality Solution. Delivered. Bad Power Quality arise from power system's interaction with power surge & harmonic load. Power Quality Solution eliminates equipment tripping and failure. If a power system is susceptible at a point possibilities of power quality tripping, resonance and CMV failure are limitless and are as dynamic as the fluctuation in the power system impedance along with its load demand and harmonics distortions. An electrical power system at the threshold of a harmonic resonance condition is like a stormy sea.

Energy Conservation has become a widely-accepted phenomenon worldwide. Yet, many times we defer the decision for our own industry till it leads to some exigency or higher energy bill.
Unless, through an energy audit, it is determined where the actual energy enters and leaves within the plant, it is impossible to determine where to direct the conservation efforts. Power System Optimization through TPM method. Total Power Management: Business dynamics many a times necessitate reexamination of existing power distribution system for a retrofit modification or upgradation on merits. 1. Retrofit, upgradation or expansion that need major equipment addition or modification 2. Installing co-generation or self-generation power plant. 3. Reducing cost and enhancing profitability through resource optimization through Total Power Management (TPM) concept Conventional engineering design approaches with standard data gathering and extrapolation method that invariably leads to a lower Load Factor design that not only creates an energy guzzling infrastructure but increases initial project investment cost and equipment footprint.
