GE Numerical Relays for the generator protection are essential as the Generator is one of the most significant elements of the power system and is the main source of generating power in the whole system. These generators are open to all kinds of stresses that are imposed on the machine’s insulation. Also, some other factors are mechanical forces on the machine, and also temperature rise. Preventive measures are essential against these overloads and other abnormal conditions. GE Generator protection devices offer Industries comprehensive solutions for safeguarding, controlling, and monitoring the generator’s assets.
The generator requires reliable protection for maximum life in the generating facility as well as for the safety of generating units. GE’s generator protection products provide industries with innovative solutions and maximize asset reliability and operational life with advanced automation. They provide load shedding solutions, protection & control to the utility generators. These devices also guarantee a secure interconnection of renewable energy sources with synchronization.
Type of Generator Protection Provided By GE
1. Large Size Generators (>40MVA)
Multilin G60
Multilin G60 is built on the industry-leading UR platform they provide reliable protection to the medium as well as large generators. It also includes combined-cycle generators, large steam & combustion turbines, and multi-circuit hydro units. These devices can also be used on pumped storage generators without any switch in the CT secondary circuitry. The G60 offers advanced communication with a fully managed Ethernet switch which helps in reducing network installation costs and complies with industry-standard communication protocols. They provide secure, high-speed protection elements for complete generator protection.
2. Small to Medium Size Generators (< 40MVA)
Multilin 889
The Multilin 889 relays belong to the Multilin 8 Series protective relay and are specially designed to provide better protection, monitoring, control, and also management generators. They also protect in-zone transformers which are used in both industrial as well as utility applications. The Multilin 889 delivers advanced, high-speed protection, flexible configuration capabilities, and extensively customizable programmable logic to enhance the operational performance and maximize the life of critical generators. The device is available with the best technology and up-to-date communications. The Multilin 889 devices support IEC 61850 Edition 2 assuring simplified device integration. They have dual communication ports IEC 62439/PRP, allowing users to achieve zero latency in communications. Multilin 889 provide high-reliability network architectures, providing complete asset monitoring and control.
3. Ground Protection
Multilin GPM-S & GE Numerical Relays
Stator ground protection works in an amalgamation with GE’s Multilin G60 and MiCOM Agile P345 offering protection from stator ground fault. They safeguard the equipment and are functional during generator start-up, run and stop conditions. In the stator ground fault protection, 20Hz voltage is injected to detect ground faults at any point across the winding and protecting the complete stator winding and qualifying early detection of stator ground fault conditions. It detects ground faults via 100% of the stator winding including the neutral point. They are especially for operating with industry-leading products G60 and P345 Generator Protection Systems. We provide Genuine Ge Numerical Relay for Generator Protection.
4. Special Applications & GE Numerical Relays
Multilin G30 & GE Numerical Relays
Multilin G30 is a part of the UR Family of protection relays providing protection to small-sized generators, medium-sized generators, and unit transformer protection. They come with a large colour LCD display and also with PMU and process bus. Developed on the industry-leading UR platform, the Multilin G30 provides advanced protection to small and medium-sized steam. They also provide protection to combustion-turbine generators as well as hydraulic. These devices are also well operatable for applications that have the same zone of protection for both the generator and transformer. They provide all required protection in one device. The Multilin G30 delivers advanced communication with an Ethernet switch while keeping standard communication protocols IEC 61850.
They provide complete protection for small to medium-sized generators as well as transformers comply with advanced IEC 61850 Ed. 1 as well as Ed. 2 certified implementations, and complete settings through SCL files with flexible process bus support (IEC 61869 IEC 61850-9-2LE and IEC 61850-9-2 Hardfiber). It assures interoperability, and device managing optimization and also reduces the cost of ownership. Get Reliable GE Numerical Relay to improve your protection system.
