Numerical Relays Schneider-1

Schneider Easergy MiCOM P341 Interconnection protection relay offer the protection requirements necessary for operating machines in parallel with the main power supply network. Models available: MiCOM P341, MiCOM P922 G
Easergy MiCOM P341 Interconnection protection relays can be customized to meet the specific needs of the intended application. They offer complete, cost-effective and highly reliable protection for operating machines.

The Schneider Easergy MiCOM P341 also includes Dynamic Line Rating (DLR) protection to optimize transmission line capacity. Gains of 50% or more can be achieved, depending on the environmental conditions, enabling more Distributed Generation (DG) such as windfarms to be connected to the grid by taking into account the real time weather conditions to calculate the line rating compared to using the fixed summer/winter line ratings. DLR is a cost effective alternative to reinforcing overhead lines to increase capacity and there are also benefits to the wind farm owner in that higher revenues can be made with a higher line rating.

Extensive multi-functions and user-friendly logic
This multi-function relay range ensures flexible, reliable integration of protection, control, monitoring and measurements for a wide variety of system applications. Users can create complex protection schemes by using Easergy MiCOM''''s powerful, user-friendly logic.
In addition, a quality choice of industry standard protocols are available, facilitating integration into both new and existing network control systems.

Flexible communications and cost-effective solutions
The Easergy MiCOM relay family''''s extensive protection functions meet the requirements for most interconnection and DLR protection applications and provide them with cost-effective solutions. It also offers flexible communications options.

An arc flash is a mass of heat and pressure caused by a switchgear fault, not only does it cause power outages but it can also result in loss of business, extensive material damage and can seriously jeopardise the safety of operational staff. VAMP’s arc detection and protection system measures fault current and light via arc sensor channels and should a fault occur, minimises burning time by quickly cutting off the current feeding the arc. Traditional arc protection methods do not provide fast enough protection and short arc burning times are critical, especially when the arc develops during maintenance work on the switchgear, jeopardising personal safely and life. The unique arc fault functionality adds a new dimension to the total safety of the installation and the reliability of the power system protection. Secure your assets, the safety of staff and the future of your power system today with VAMP’s ultra-fast arc protection products.

The latest offering from Schneider Electric is the innovative VAMP 321. Combining the reliable technology of the VAMP 50 and 200 series and that of the VAMP 221 arc flash protection system, the VAMP 321 offers a safe and technologically advanced solution for protection and control, in just one product.

Transformers are high capital assets in electrical power systems. Elimination of all electrical and mechanical stresses, although desirable to preserve transformer life, is impractical. Adaptive techniques to measure, alarm (or trip) and advise on cumulative service can help to schedule preventive maintenance before a costly failure occurs. Internal faults are a risk for all transformers, with short-circuits dissipating the highest localized energy. Unless cleared quickly, the possibility to rewind windings reduces and core damage may become irreparable.

GE's P642, P643 and P645 address all these issues, preserving service life and offering fast protection for transformer faults. A transient bias technique has been included, enhancing relay stability and CT requirements. Hosted on an advanced IED platform, the P64x incorporates differential, REF, thermal, and overfluxing protection, plus backup protection for uncleared external faults. Model variants cover two and three-winding transformers (including auto-transformers), with up to five sets of 3-phase CT inputs.

Key benefits:

• Backup and logging of through faults 
• Simple settings – wizard requires only nameplate data 
• Integrated backup overcurrent per winding or CT input - optional directionalizing when relay fitted with a 3-phase VT  
• Ordering the 3-phase VT permits full monitoring and measurement of power and energy quantities 

Main characteristics:

• Current loop analogue inputs [CLIO] and analogue outputs [RTD] for remote monitoring 
• Optional single or dual redundant Ethernet available for IEC 61850 or DNP3
• Transient biasing reduces CT knee point dimensioning by typically 25% compared to historical applications
