Our working
knowledge can cover next manufacturers of
protective IEDs:
● ABB,
● SIEMENS,
● SCHNEIDER ELECTRIC,
● ALSTOM / AREVA,
● and others.
In case of a knowledge gap, we complete this with additional courses or
with partner companies.
Knowledge and
experiences gathered during past work, allows us to offer next
services:
● verification and testing of AIS and GIS primary equipment (circuit
breakers, power transformers, current and voltage measuring
transformers, harmonic filters, shunt reactors, etc.),
● testing cable connections between cabinets and systems,
● functional testing of electrical cabinets and systems,
● checking the isolation of electrical equipment (cables, primary and
secondary equipment, wiring in the cabinet, etc.),
● testing protection and control relays (secondary systems) by checking
the configurations and settings of protection functions,
● refurbishment of substations,
● selection of secondary equipment,
● as-built documentation at end of work,
● interlocking control,
● regular annual inspection of electrical systems in the energy sector;
● design and production of configurations for protection and control
relays of all voltage levels and schemes,
● commissioning of power equipment and systems,
● periodic maintenance of electric equipment (yearly testing),
● testing of signals against the control system (SCADA, RTU),
● verification of commands from the control system (SCADA, RTU),
● establishment and verification of horizontal and vertical
communication (LON, IEC61850),
● testing of digital substation MU devices (Merging Units) and SV
(Sampled Values).
For our work we
are fully equipped with:
● PPE (Personal Protective Equipment)
● True-RMS industrial logging multimeter
● Loop calibrator
● Insulation tester
● Universal relay test set
All our working equipment carries valid calibration certificate.
