Already heard about the (r)evolution in testing electrical energy systems?
COMPANO 100 – Easy-to-use test set for basic testing duties in electrical energy systems
Thanks to its flexibility, COMPANO 100 can truly be called an engineers toolbox: The device combines the power of a primary injection test set, a secondary injection test set, and a basic relay test equipment. COMPANO 100 is right at your side to support you and your technicians with all basic protection tasks especially in low- and medium-voltage environments. Its battery power makes searching for mains supply or tripping over extension cords a thing of the past. The versatile test equipment is the ideal companion for:
- single-phase testing of protection relays
- wiring and polarity checks
- burden measurements
- basic primary injection testing
- ratio checks on instrument transformers (CTs / VTs)
- as well as micro-ohm resistance testing.
Ready for your needs!
Designed as universal testing tool for protection testers on-site,
COMPANO 100 covers a wide range of applications.

Want to check low- and medium-voltage switchgear?
Use the integrated timer of the COMPANO 100 test set to measure the open and closing times of medium-voltage circuit breakers (1 kV to 36 kV). Additionally, the circuit breaker contact resistance can be tested with the built-in micro-ohm function.

Have to test the overcurrent relay at the 10 kV distribution level?
With COMPANO 100, you don't need a dedicated relay test set for basic protective relay testing. The test equipment allows you to perform single-phase protection tests on overcurrent relays for medium and high voltage systems. Thanks to the independent current and voltage source with freely adjustable phase angle, you can even test directional and distance protection relays. Voltage and frequency protection is covered as well.

Need to test the burden of a voltage transformer or current transformer (VT / CT)?
Use the test set's secondary injection to check and verify the burden of instrument transformers and avoid problems due to over- or underburdened VTs or CTs.

Want to check the readings of meters, relays or even SCADA systems?
With COMPANO 100 you can inject current and voltage on primary or secondary side of your system and check the readings for correctness.

Straightforward configuration
Electronically controlled sources allow you to directly get the current or voltage you want. No need to reconfigure your test set depending on the burden like on variac-based test sets.
Benefit from your new testing companion

“The slick thing about COMPANO 100 is that it is battery-powered. Because on a construction site, the last thing the electricians do is hook up the AC power on-site.”
