is an analysis of power reliability and power quality of your electrical power distribution system to ensure electrical safety and quality of power supplied to your facilities.
The quality of the electrical system greatly affects the equipment performance and worker safety.
Electricity system infrastructure that is not in accordance with the standards and poor quality electricity can cause a potential danger of fire and explosion.
Some of the symptoms of disruption in the electrical system are as follows:
- Overheat on power cable
- Overheat on transformer, capacitor bank and electric motor
- Interference to the control system (PLC, inverter, VSD, power supply)
- High current on neutral cable, which can endanger workers and equipment
- Static electricity in flammable areas, which can cause fire and explosion
We do online measurement and analyze by engineering calculation and software modelling analysis.
Power Quality and Electrical Safety Assessment
- Power factor, frequency, and voltage disturbances
- Power disturbances
- Harmonic distortion analysis
- Load flow analysis and power loss calculation
- Power reliability
- Power quality effect to machine performance and sensitive eqipment
- HIRARC on electrical power distribution system
- PQAC (Power Quality Area Classification)
Arc Flash Hazard Analysis
- Arc flash boundaries
- Incident energy possible
- Flash protection boundaries and PPE required.
- Hazard risk categories
Monitor and analyze the supply of power entering the electricity system, evaluate the detection of power disturbance that affect to the system and equipment, and mitigate the power disturbance to improve the equipment performance and electrical safety.Monitor and analyze the supply of power entering the electricity system, evaluate the detection of power disturbance that affect to the system and equipment, and mitigate the power disturbance to improve the equipment performance and electrical safety.
Poor power quality can cause electrical faults, jeopardize personal safety, damage or reduce the life of electrical and electronic equipment, cause an increased fire hazard, and reduce equipment performance and productivity.
(Std. Ref. NFPA 70B Chapter 27)
One of Power Quality problem is Harmonics. Harmonics in power system may cause:
• Excessive neutral current
• Overheating of transformers, motors, generators, solenoid coils.
• Nuisance operation of protective devices
• Unexplained blowing of fuses on power factor correction capacitors
• Unusual audible noise in electrical switchgear
• Mis-operation and failure of solid-state electronic equipment due to waveform distortion
• Loss of data on computer system
