Directly installed on generator terminals

Rated nominal current up to 5,000 A
All-in-one solution integrating the generator neutral and main terminal boxes, protection system of the auxiliary transformer and generator circuit-breaker
Minimizing interface
HIGS helps you reducing interfaces and space requirement while increasing your protection level
With its direct connection and installation onto the generator, the HIGS decreases the number of interfaces and saves valuable space with integration into a single system of the generator neutral and line accessory compartment, the protection system of the auxiliary transformer and the generator circuit-breaker. The highly integrated generator switchgear (HIGS) is rated for application up to 5.000 A continuous current and short-circuit ratings up to 72 kA, specifically for Siemens industrial turbines SGT-600 to SGT-800 as well as for steam turbines SST-400 to SST-600. It can also be adapted for other gas and steam turbines. With its air-insulated, metal-enclosed and non-phase segregated design, this generator switchgear integrates vacuum generator circuit-breaker (tested as per IEC/IEEE 62271-37-013) and optionally: line disconnecting switch, earth disconnecting switch on generator side and/ or transformer side, instrument transformers, surge arresters, protection of auxiliary transformer and neutral point treatment.

The most exhaustive and compact solution to protect your power unit:
• Directly installed at generator terminals
• Matches dimensions of replaced conventional generator terminal boxes
• Reduces the number of interfaces and saves space
• Suitable for indoor and outdoor installation
