MV/LV substations, line bays, transformers, metering circuits and station automation systems.
Testing • Protection • Transformers • VLF / PD
Precision and safety in industrial power systems.
Since 2018 we have been delivering testing, protection and diagnostics services for utilities and industrial customers – from MV/LV switchgear commissioning to transformer diagnostics and protection relay testing.
About us
Feniks Energy is a team focused on power system automation, electrical testing
and diagnostics. We operate at the interface between utilities, industry
and modern PV installations.
We combine on-site experience with advanced test equipment – from Omicron and Megger
systems through to full protection relay testing and transformer diagnostics.
Our main goal is to ensure safety, reliability and correct operation
of power systems at every stage of the project.
Who we work for
We support investors and asset owners throughout the full life-cycle – from design and commissioning to periodic diagnostics and fault investigation.
EPC & contractors
Support with commissioning, final testing, protection settings and documentation for hand-over.
Industrial plants
Plant substations, power distribution, modernisations and diagnostics during outages or emergencies.
PV & renewables
Container substations, MV transformers, connection bays, MV cable testing and earthing verification.
Why work with us?
We combine real-world substation experience with advanced diagnostics and protection relay know-how. The outcome for the client is simple: a safe and correctly operating installation and clear documentation after completion.
Hands-on experience
Experience from MV/LV substations, PV farms and industrial sites. We understand real issues – from wiring errors to complex automation faults.
- Hundreds of tests and commissioning jobs
- Work on live sites and new installations
- Technical support already at design / execution stage
Professional equipment
We work with world-class test sets used by utilities and specialist labs. This ensures reliable results and clear technical conclusions.
- Omicron CMC / FREJA, Megger TRAX, CT Analyzer
- VLF + PD for MV cable testing
- Certified instruments for resistance, earthing and insulation
Safety & compliance
All tests and settings are carried out in line with applicable standards and DSO requirements. We care about personnel safety and long-term reliable operation of the installation.
- IEC / EN standards for LV and MV equipment
- Compliance with Polish DSO procedures
- Strict adherence to safety rules on site
Clear documentation
After completion you receive a full test report package that can be directly attached to project documentation or DSO submissions.
- Readable test protocols and results
- Protection settings and configuration description
- Technical conclusions and recommendations
On time & reliable
We understand that delays cost money. We plan our work so as not to block other trades on site and to keep agreed deadlines.
- Work according to agreed schedule
- Flexibility when conditions on site change
- Real support also after project completion
Tools + knowledge
We do not “just” test – we identify root causes and suggest possible corrective actions, especially for hard-to-catch faults and misconfigurations.
- Fast fault localisation
- Support for commissioning and retrofit projects
- Engineering-driven, not marketing-driven approach
Services
Installation, commissioning and testing services for utilities, EPCs, industrial plants and PV installations – from a single switchboard up to complete MV/LV substations.
Testing & measurements
- Earth resistance and continuity testing (PV structures, substations, MV/LV switchgear)
- Insulation resistance tests of primary and secondary circuits
- Verification of current and voltage circuits (injection test sets)
- Polarity, phase sequence and wiring checks
- Loop impedance and connection resistance measurements
Protection & relay testing
- Configuration, setting and testing of protection relays (Schneider, ABB, Siemens, JM-TRONIK, Elektrometal, uREG, Woodward, C&C and others)
- Verification of time-current characteristics and relay coordination
- End-to-end tests for DSO requirements
- Logic, interlocking and signalling tests
- Functional testing of MV and LV switchgear before energisation
Switchgear & apparatus diagnostics
- Dielectric tests of MV switchgear and insulation strength checks
- Circuit breaker tests – operating times, pole discrepancy, contact resistance
- CT/VT testing – ratio, burden, characteristics and resistance
- Condition assessment of primary circuits and switching devices
- Auxiliary circuit checks (drives, coils, interposing relays)
Transformers & cables
- MV/LV transformer diagnostics – magnetising currents, winding resistance, tan δ, frequency response, tap changer tests
- Insulation condition assessment and cooling system checks
- VLF and PD tests for MV cables – diagnostics, fault location, post-repair verification
- Continuity checks of screens, earth wires and terminations
