Products Check out our wide range of products.

Amperis supplies electrical test and measurement equipment for substations, power utilities and industrial electrical systems, with deliveries to customers in 58 countries. Our catalogue covers the complete diagnostic chain for medium- and high-voltage assets — insulation, transformers, circuit breakers and SF6, power quality, thermography, partial discharge, relays and battery systems — together with calibration, technical advice and after-sales support. As an independent vendor, we match the right instrument to your application, standard and budget across several technologies rather than a single product line.

What our catalogue covers

Insulation resistance meters apply a controlled DC voltage (ranges from 1 kV to 15 kV) to assess the condition of insulation in transformers, cables, motors and switchgear.
Power network analysers record voltage, current, harmonics and disturbances for power-quality studies to IEC 61000-4-30.
Transformer testing covers turns ratio, winding resistance and tap-changer checks to IEC 60076.
Circuit-breaker and switch testing measures timing and contact resistance, and includes SF6 gas analysis and leak detection.
Infrared and corona cameras locate hot spots and corona discharge on energised equipment without interrupting service.
Partial discharge detection finds insulation defects before they cause failure, to IEC 60270.
Relay testing verifies protection relays for safe, reliable operation.
Battery maintenance and charging tests and conditions stationary battery banks to IEEE 1188.
Multifunction installation testers check low-voltage installation safety to IEC 61557.

How to choose the right equipment

Start from the asset and its voltage level, then the standard you need to satisfy and where you will work:

Asset and voltage: a 1 kV tester suits installations and telecom; 5 kV covers industrial motors and cables; 10–15 kV is intended for high-voltage substation diagnostics with strong noise immunity.
Standard: confirm the IEC, IEEE or NETA procedure your test must follow.
Environment: field-portable versus laboratory bench, ingress protection and battery autonomy.
Reporting: on-board memory, software and connectivity for traceable records.

Frequently asked questions

Does Amperis ship internationally?

Yes. We supply electrical test and measurement equipment to customers in 58 countries, handling export documentation and logistics from our base in Lugo, Spain.

Do you provide calibration and after-sales support?

We provide calibration, commissioning guidance and post-sales technical support, so instruments stay traceable to the applicable standards throughout their service life.

Yes. As a specialist vendor we compare instruments across several technologies and match them to your asset, the standard you must meet and your budget. Tell us your application and we will advise.

How do I request a price or a quotation?
