T&T Sistemi’s engineering team works on the design, commissioning and maintenance of electrical and instrumentation systems, with system integration delivered on live, demanding industrial sites.
Integration is executed around the same asset, in coordination with the automation, controls and mechanical teams.
Electrical system design
- Feasibility studies, development and project coordination
- Design of medium- and low-voltage systems (MV and LV), including substations and distribution boards
- Compliance with IEC 61936 in medium-voltage installations, with verification testing
Electrical commissioning and maintenance
- Commissioning and startup of substations and motor control centers (MCC)
- Calibration of protection and control relays
- Parameterization of generator automatic voltage regulators (AVR) and variable frequency drives (VFD)
- Preventive and corrective maintenance of low- and high-voltage panels
- Power-quality verification and battery-bank certification
- Insulation resistance testing and high-voltage cable testing (hipot)
Instrumentation
- 100% automated calibration and metrological testing (IoT 4.0), with ABEND-certified personnel and standards traceable to RBC/Inmetro
- Instrumentation commissioning, with loop testing, startup and assisted operation
- Validation of Foundation Fieldbus (FF) networks, HAZOP, cause-and-effect matrix and databook per SOP/SSOP
- Vibration analysis with the TK3 test kit, shaker table and ADRE data collector (Bently Nevada / Discovery)
Workshop in São José dos Campos
At its in-house electrical and instrumentation workshop, T&T Sistemi carries out valve testing, actuator calibration, metal fabrication and prototype certification.
Valve testing
- Mechanical and instrumented valves: seat and shell tests, hydrostatic testing, leak-tightness and cavity relief tests
- Pressure relief and safety valves (PSV), in line with NR-13 requirements
- Leak-tightness of internal, self-relieving and double piston effect seats, per API 6D, API 598, BS 1868 and BS 1873
Actuators, metal fabrication and prototypes
- Calibration and automation testing of electric, pneumatic, electro-hydraulic, motorized and self-operated actuators, with network addressing
- Metal fabrication: spools and supports
- Certification of mechanical and automated prototypes, with 3D coordinate measuring machines
Instrumentation and network bench
- Foundation Fieldbus (FF) and Profibus PA/DP communication networks
- TREX communicators
- Fluke 754, 725 and 719 multi-calibrators, among others
- Megohmmeters and oscilloscope
- Thermal bath furnace
