Field-convenient three-phase relay testing with an all-in-one Windows CE design.
Field testing without a laptop
The AK-6 is a three-phase relay test set with an AC and DC voltage source, high-power current burden and AC/DC auxiliary supplies, in an all-in-one design with a built-in Windows CE system, a 6.4-inch TFT display, panel keyboard and rotary encoder. It runs automatically or manually across its five test modules — DC test, AC test, distance test, harmonic test and frequency protection — with RJ45 and USB for updates and data transfer.
High power, high accuracy
The unit provides 4×300 V (4×110 VA at 0-300 V) and 3×35 A (3×450 VA at 0-35 A) for medium-voltage level tests, with a guaranteed accuracy of 0.07 % of reading plus 0.03 % of range at 0-130 V and a frequency range up to 1000 Hz. Amplitude, frequency and phase are independently and continuously adjustable.
Main features
- All-in-one design with Windows CE, 6.4-inch TFT, keyboard and rotary encoder.
- Five test modules: DC, AC, distance, harmonic and frequency.
- Complete self-protection against wrong wiring, short circuit and overload.
- Field-ready: the instrument can be placed vertically to save space.
- RJ45 and USB ports for firmware updates and data transfer.
- Lightweight design for on-site work.
Applications and delivery
Applications
- Testing of protection relays at medium-voltage level.
- Distance, harmonic and frequency protection testing.
- DC and AC injection with time measurement.
- On-site commissioning and periodic maintenance.
Ready for the field
The AK-6 combines high burden with a compact, lightweight case, complete alarm indication against wrong wiring, open or short circuit, overheating and overload, and the option to work vertically where bench space is limited.
