Power-sector laboratories, planned and specified to the applicable IEC and IS test standards.
We plan, specify and commission short-circuit, high-voltage and transformer test laboratories, from the first feasibility study to commissioning, test procedures and staff training. We also prepare the documentation a laboratory needs when it applies for accreditation.
Three kinds of laboratory, one engineering team.
Short-circuit lab for switchgear
For MCBs, MCCBs, RCCBs and circuit breakers. Fed directly from an 11 kV or 33 kV grid supply, so no generator is needed for the lower current bands.
- Current
- 1.5 to 10 kA
- Supply
- 11 / 33 kV grid
- Standards
- IEC 60898-1/-2, IEC 60947-1/-2, IEC 61010-1
- Planned for
- Accreditation readiness (client applies)
Short-circuit lab for distribution transformers
Tests a transformer's ability to withstand a short circuit, both dynamic and thermal. Powered by a motor-generator set with flywheel, so the grid is not disturbed.
- Rating
- Up to 250 kVA, 11 kV
- Source
- 2.5 MVA, 11 kV MG set
- Tests
- Dynamic 9 shots × 500 ms, thermal 2 s
- Standards
- IS 2026 Part 5, ISO/IEC 17025:2017
Power transformer test lab
Routine, type and special tests for large power transformers, in an electromagnetically shielded hall with an AIS or GIS test plant and heavy handling.
- Rating
- 50 MVA / 132 kV to 500 MVA / 420 kV
- Handling
- 400-ton transport, EOT crane
- Processing
- Vapour-phase drying, oil filtration
- Standards
- BS EN 60076, ISO/IEC 17025:2017, Power Grid specs
One team from the first survey to an operational laboratory.
You can engage us for the whole journey or for a single phase, such as a DPR or an independent tender evaluation.
We specify every link in the test circuit.
A short-circuit test lasts a fraction of a second, so every element has to be sized, timed and protected together. These are the systems we design and specify.
Labs we have studied, designed or specified.
Distribution transformer test centre
Feasibility study and DPR for a generator-based short-circuit lab for distribution transformers up to 250 kVA, 11 kV, built around a 2.5 MVA MG set.
Power transformer HV test laboratories
Consultancy for power transformer test labs at 50 MVA / 132 kV and 500 MVA / 420 kV, with about 200 capital items specified, from the shielded hall to the test plant.
Low-voltage switchgear short-circuit facility
Feasibility report for a grid-based short-circuit lab testing MCBs, MCCBs and breakers in the 1.5 to 10 kA band, planned so the client can seek accreditation.
