Testing high-burden electromechanical relays, numerical relays and IEC 61850 substation IEDs in the same campaign takes a test set with powerful, accurate analogue outputs and a fibre interface for the standard. The AK-30 injects up to 6×30 A (450 VA per channel), 3×60 A (850 VA) or 1×100 A (1200 VA) and up to 7×300 V, with a guaranteed voltage accuracy of 0.07 % of reading + 0.03 % of range; the AK-31 rises to 6×32 A and 4×310 V and adds two 100Base-FX fibre ports for IEC 61850, 13 low-level outputs and GPS, IRIG-B and IEEE 1588 synchronisation.

Advantages
Universal, IEC 61850 ready
Compatible with the IEC 61850 standard, with independent voltage sources, current sources and a relay power simulator, plus a DC source that can be used at the same time.
Every generation of relay
It tests all generations and types of relays — current, voltage, frequency, power, impedance, harmonics and distance — including high-load electromechanical relays with very high power demand.
Protected and reliable
Complete self-protection and alarm indicators cover overload, overheating, short circuit, open circuit and incorrect connection.
Field-proven workflow
Current transformer wiring checks, GPS-triggered testing and PC control over RJ45 Ethernet, with RIO / XRIO import and export.
A model for the job
AK3030i, AK3063i and AK3066i cover 3×30 to 6×30 A and 450-850 VA; the AK-31 family adds AK3130i and AK3163i with 4×310 V / 124 VA outputs.
Applications
- Testing of current, voltage, frequency, power and impedance relays.
- Distance and harmonic protection, including high-load electromechanical relays.
- IEC 61850 substation testing.
- End-to-end testing with GPS synchronisation.
About the product
The AK-30 has 10 channels and the AK-31 has 13, both with a DC source usable at the same time; the voltage sources, current sources and relay power simulator are independent, controlled from a PC over RJ45 Ethernet with RIO / XRIO import and export in a robust, lightweight design.
