(Free Air Delivery) Test for all air compressorsLeak Test for compressed air systemAir leak points identificationMatching the demand side management with supply5. Proper cooling and appropriate air intake of Air Compressors.MotorsMotor Loading SurveyEvaluation for possibility for VFD Efficiency calculation for motors Matching the proper rated motor at proper positionImproved ControlsReplacement with Energy Efficient Motors PumpsEfficiency Calculation of pumps Evaluation for possibility for VFDs Evaluation for capacity variationOperating pumps near to best efficiency pointsModify pumping system to minimize lossesInstalling auto start stop pumps Diesel Generator SetsChecking of ventilation arrangement for the DG unit room Checking of loading pattern of DG Sets Checking adequacy of capacity of DG set w.r.t to actual requirement Checking of type of load taken on DG and evaluating its necessity Checking noise level of DG Physical verification of wiring of DG Checking of effectiveness of cooling system of DG Checking of per unit power generation w .r.t consumption.TransformersThree phase power analysis (each phase voltage, current, power factor, power-Kw, kVA, kVARh etc.) of Running Load of transformer. Load test of transformer To check adequacy of transformer w.r.t. required capacity To check protection provided at the location of transformer To check grounding/earthing of transformer Assessment of CapacitorsTesting of present capacitor banksLocating capacitor banks at appropriate locationRequirement for any new capacitor bank.Installation of capacitors on motors having inductive load.Cooling TowerImprove cooling efficacy by evaluating water flow to air flow ratioReview condition of fills,Rationalization of number of cells in operation, improvement in fan efficiencies and rationalization of operationHeat ExchangersIdentifying fouled heat exchangersReduce demand of utilities like steamCooling waterChilled water and chilled brine by heat integration by Pinch AnalysisHVACDryers(efficiency, Safety, performance) AHU (efficiency, Safety, performance) Chiller system, (efficiency, Safety, performance) Duct System (efficiency, Safety, performance)Lightening SystemMonitoring of lighting lux levels Comparing existing lux levels with standards Optimization of feeder voltagesStudy of feasibility of installation of energy efficient lighting Power Quality AnalysisTo ascertain electrical load utilization (separate for each electrical meter) Check on incoming main (separate for each electrical meter) - R, Y, B phase & Neutral Detail Harmonic & transient study with recommendations. Checking face balance at different locationsSegregation of power at different locationsAssessment of Electricity Tariff planData collection on total connected load To check whether sanctioned load is less than the connected load To check whether they has applied for additional load To check whether branch has paid any penalties for excessive load Thank You
