Three-phase relay test set with up to 120 A of injection
Testing differential and distance protection or high-burden electromechanical relays takes a relay test set with more than three current channels and outputs that can be grouped for high current. The AK-10 offers up to 13 channels —6×20 A of current and 7×130 V of voltage, or 300 V on the 'i' variants—, groups the current into 3×40 A or 1×120 A and keeps a guaranteed accuracy below 0.14 % of reading + 0.06 % of range, with GPS synchronisation and its own Windows CE control on a 6.4-inch TFT display.

Advantages
A complete relay test bench
An AC and DC voltage source, an AC current source and an AC/DC auxiliary supply share one all-in-one design with Windows CE, a 6.4-inch TFT display, mouse and keyboard, and up to 13 output channels.
Power and precision together
The amplifier delivers 6×420 VA at 0-20 A, 3×520 VA at 0-40 A and 1×1000 VA at 0-120 A, with a guaranteed accuracy of 0.14 % of reading plus 0.06 % of range at 0-300 V and 0-30 A.
Full control of the signal
Amplitude, frequency and phase angle adjust independently and continuously on every channel, across eight selectable output configurations.
Ready for high-load relays
A built-in amplifier drives high-burden electromechanical relays, and a separate Ethernet port handles PC control and reporting.
A model for every relay
Eight models — AK1030 to AK1066 and the 'i' variants — scale the injection capacity from 3×30 A / 4×130 V up to 3×60 A with 6×30 A and 7×300 V.
Applications
- Testing of current, voltage, frequency, power and impedance relays.
- Distance, harmonic and directional protection testing.
- Wiring checks of current transformers.
- Commissioning and periodic maintenance of protection systems.
About the product
The AK-10 is an all-in-one design with a built-in Windows CE system, a 6.4-inch TFT display, mouse and keyboard and a separate Ethernet port for PC control; the family covers eight models (AK1030, AK1040, AK1063, AK1066 and their 'i' variants) so the number of channels and the injection power match the relay under test.

Frequently asked questions
What is the difference between the AK-10 models with and without 'i'?
The voltage and, on the six-channel models, the current. The AK1030, AK1040, AK1063 and AK1066 work with 130 V outputs; the AK1030i, AK1040i, AK1063i and AK1066i variants go up to 300 V (4×300 V or 7×300 V), and the AK1063i and AK1066i extend the current to 6×30 A and 3×60 A.
Which software functions and file formats does the AK-10 support?
The AK-10 software controls 10 analogue generators independently, shows the vectors online, automatically compares the actual characteristic with the expected one, models the power system for dynamic testing, imports and exports RIO / XRIO, plays back COMTRADE files and generates the test reports automatically.
What can it test?
Current, voltage, frequency, power and impedance relays, including distance, harmonic and directional protection, plus current transformer wiring checks.
How much can it inject?
Up to 1×1000 VA at 0-120 A, 3×520 VA at 0-40 A or 6×420 VA at 0-20 A, with up to 13 output channels.
Does it need a PC?
No. It has a built-in Windows CE system with TFT display, mouse and keyboard, and a separate Ethernet port for PC control when needed.
Which model should I choose?
One of eight: AK1030, AK1040, AK1063, AK1066 and their 'i' variants, according to the channels and injection power required.
Can it drive electromechanical relays?
Yes. The built-in amplifier handles high-burden electromechanical relays with very high power demand.
