GL 313
Live tank by-pass switch for series capacitor bank applications
GE’s GL 314 By-Pass Switch (BPS) is designed to close very fast and protect series capacitor banks in case of a fault in the overhead lines. It is equipped with excelled live tank circuit breaker technology such as the third-generation self-blast interrupter chambers and spring-operated mechanisms (FK). These field–proven interrupter chambers operate on the optimized self-blast principle. The FK3 type mechanisms equip the entire range of circuit breakers with more than 180,000 references worldwide.
The GL 314 BPS is field-proven and time-tested, providing high mechanical endurance and very low restrike probability according to IEC 622271-100 class M2 & C2. GE’s live tank circuit breakers provide a high level of reliability, even under extreme conditions and climates, and allow for quick, easy installation and commissioning with long intervals between maintenance.

High Quality Components
The GL 313 live tank circuit breaker provides high reliability based in part on high quality components, including:
- Interrupter chamber with integral double motion technology and self-blast system
- Pressure relief system for passive protection of both substation and personnel
- Field-proven, temperature-compensated density monitor with two-stage transducer and three-color dial
- Easy access to the SF6 filling connection (type DILO)
- SF6 non-return (check) valve on each pole column
- Protected opening springs inside each pole column
- Hot-dip galvanized steel parts
- Mechanism housing made completely of aluminum
- Reliable spring-operated mechanism with position indicator clearly visible from outside
Installation and Maintenance
- Preset at factory before shipping; no adjustments necessary during installation and commissioning
- Pole units pre-filled with SF6 at factory before shipping
- Independent disassembly of the interrupter chamber without having to remove the entire pole column
Testing
Our live tank circuit breakers meet the requirements of national and international standards. This has been confirmed by comprehensive type tests according to the latest IEC and ANSI standards.
Quality
The entire development and production procedures for our live tank circuit breakers are fully compliant with the latest ISO 9001 ISO 14001 and OHSAS 18001 quality standards. This ensures the high quality of our products and services, which is confirmed by regular audits.
