Protection Relay Testing

HEXAN II is a three-phase test set that can be operated from a PC or from a hand-held console. Being a modular system, it can be configured from the start to suit individual users, and be later upgraded and updated. The Hexan's versatility means that it can test and calibrate both Electronic and Electromagnetic relays. All the usual test and calibration functions are easily available, and the associated Manusoft PC software is exceptionally user-friendly. HEXAN II uses the latest technologies to combine a power of up to 300 V & 25 amps per phase (175 VA) in a small package weighing only 13kg. The NEW G59 version is tailored to G59 work but has many other applications.

HEXAN C has the same functionality in a larger, lower-cost version which incorporates the manual control console in the front face. It can be operated either with this console or from a PC.
