Edge Electrics Private Limited

• Verify compliance with established standards (regulations, internal policies and industry wise standards of practice )
• Identify deviation from designed and planned operating and maintenance procedure and standards
• Identify plant condition or operating procedures that could lead to an accident and significant losses to life or property
• Ensure that the plan and operating and maintenance procedures match the design intent and standards
• Keep the operating personnel alert to the process hazards & Review operating procedures for necessary revisions
• Seek to identify equipment or process changes that could have introduced new hazards
• Ultimate application of new technology to existing hazards & Review adequacy of safety inspections
• Look for major risk situations recommend measures to improve overall safety performance of the plant

• Goals of Team Edge Technologies in Safety Audit are Identifying potential electrical hazards to prevent or minimize loss of life and property by electrical causes such as short circuits, overloading, loose electrical connections etc
• To identify potential electrical hazards, flaws in design system, maintenance system, etc.

Team Edge Process Flow:

• Defining scope of Electrical Safety audit based on the specific requirement.
• Physical inspection of the plant.
• Reviewing the role of electrical safety in the total safety system.
• Review of protection devices / system of the electrical installation.
• Review of adequacy of cables, motors, etc.
• Based on actual load current measurements and cable current carrying capacities.
• Examination of adequacy of plant lightning protection system as per national and international standards to suggest recommendations as per applicable standards.
• Review of the hazardous area Review of electrical accidents to identify root cause of the accidents.
• Review the EPM (Electrical Preventive Maintenance) programme in the plant and to examine the documentation, checklists, work permit.

We undertake Preventive maintenence Comprehensive & Non Comprehensive AMC’s for:

• Capacitors
• Auto Power Factor Controllers
• Thyristorized
• Electromechanical
• Active Harmonic Filters

As more and more industries opt for process automation to increase control over operations and save on energy, the use of electronic equipment has also increased simultaneously, The use of devices such as variable speed drives, rectifiers, and energy savers cause harmonics and transients in the network – thus defeating their very purpose of energy efficiency. Modern industries require automation of their operation enabling them to produce quality products and also for mass production. The conventional systems are being replaced by modern Power Electronic systems, bringing a variety of advantages to the users. Classic examples are DC & AC Drives, UPS, soft starters, etc. Since the Thyristor converter technology is rapidly gaining ground in the modern industrial plants, the power supply systems are contaminated as the ideal sinusoidal current and voltage waveforms are getting distorted. This in turn is affecting the performance of the equipment in the electrical network.

Symptoms of Harmonics Studies

• Blinking of incandescent bulbs
•  Capacitor failure.
•  Circuit breaker tripping.
•  Computer malfunction or lockup.
•  Conductor failure.
•  Failure of electronic equipment.
•  Flickering of fluorescent tubes.
•  Blown fuses.
•  Motor failures due to overheating.
•  Excessive neutral current.
•  Overheating of metal enclosures.
•  Power interference on voice communication
•  Transformer failure /Temperature Rise.
•  Buss bar Humming.
•  Cable Heating.

Effects of Harmonics:

• Increased losses and temperature rise in Cables & Transformers.
• Resonance between inductance and capacitance of the network resulting in amplification of harmonic currents in the network.
• Accuracy of measuring instruments and protection relays affected
• Communication signals distorted. Increase in Eddy Current and
• Hysteresis Losses. Increase in Noise level of Audio equipment. Buss Bar Humming Noise.
• Increase in neutral currents.
• Neutral conductor and terminal failures.
• Failure of electromagnetic loads.
• Cards Failure

Our Approach:

• Detect Harmonics in the network.
• Identification of type of harmonics, amplitude of distortion and percentage of I-THD and V-THD.
• Provide technical Specifications for Harmonic Filters.
  Supply, installation assistance and commissioning of filters.
• Performance evaluation of filters and benefits after installation if done by us.
• Provide KVAR Calculation at various levels.
• Measure neutral to earth voltages.
• Demand management.
• TEAM EDGE Technologies with their High End 3 Phase Power Quality Analyzers measures harmonics but also give concrete Solutions to the problems found.
