Our specialties
Six engineering disciplines that combine according to the system and the stage of the project.
01
Analysis of power system behavior: load flow, short circuit, stability, electromagnetic transients, power quality, equipment overduty, protection and selectivity.
02
Measurements, inspections and diagnostics to assess equipment and systems, including transformers, dielectric insulation, partial discharge, thermography and power quality.
03
Protection, automation and supervision of electrical systems, including relay settings, IEC 61850 integration, functional testing and commissioning.
04
Electrical distribution and industrial installation design, primary unit substations, motor control centers, lighting, harmonic filters and automatic capacitor banks.
05
Measurements, diagnostics and filter design to suppress electromagnetic interference, plus consulting on type approval and certification.
06
Communication networks for electrical systems, supervisory systems, teleprotection, energy metering and smart grid applications.
From study to commissioning
One system, many specialties.
In a substation, studies define limits and settings, protection and automation provide the response, communication carries the information and testing confirms it in the field. PWM works on each of these layers.
- Electrical studies
- System behavior: power flow, short circuit, stability, transients.
- Protection and automation
- Relays, IEDs, selectivity and IEC 61850 integration.
- Telecommunications
- Teleprotection, SCADA and energy metering.
- Testing and commissioning
- Measurements, diagnostics and field validation.
