Electrical Protection & Fire Safety
Earthing system audit
DEW Energy provides complete earthing audit for substations and industrial units using world class testing instruments and computer software from SES Technologies, Canada. Detailed analysis of incoming power and grounding integrity identifies distinctive problem locations and provides recommendations to enhance overall system performance.
- Earth Pit Testing
- Soil Resistivity Testing
- Advanced Earting simulation with computer software for:
- Safety Compliance
- Ground potential rise (GPR)
- Touch voltage
- Step voltage
- Fault current discharged by the grid
Why we need an advanced Earthing Audit?
- Safety compliance as per IEEE ST-80, 2000
- Smaller-area substations & higher fault levels
- More prevalent use of sensitive electronic machines/equipment
- Impact of transferred earth potentials needs to be mitigated
Infrared thermography preventive maintenance
Infrared thermography is a predictive maintenance inspection technique. Nearly everything gets hot before it fails. Infrared scanning is extremely cost effective, valuables diagnostic tool to identify excessive heat loss in systems or materials. The most popular and widely used application of infrared thermography is electrical switchgear, Motors, Panels, Transformers and Generators testing. Electrical Infrared is now an integral part of any Utility/facility manager’s predictive maintenance & Safety program.
The most popular and widely used application of infrared thermography is electrical switchgear, Motors, Transformers and Generators testing. No other commercial application has achieved the level of interest than that of electrical infrared thermography. Electrical Infrared is now an integral part of any Utility/facility manager’s preventative/predictive maintenance program.
BENEFITS OF INFRARED ELECTRICAL INSPECTIONS
With infrared thermography you identify and hence repair only what needs repairing. It helps in reduction of disassembling, rebuilding or repairing components which are in good operating condition. This type of repair is meaningless and costly.
- Prevent Fire & Failure due to overheating in Electric Panels & Machines
- Greater system security
- Increased revenue
- Reduced outage costs
- More efficient inspection
- Improved and less expensive maintenance
- Reduce spare parts inventory
Lightning & surge protection audit
