GE Grid Solutions 369 Series

Applicable application scenarios

The 369 series relays are widely used in various fields of medium and low voltage power systems due to their strong versatility and flexible adaptability, including:

Industrial power distribution systems, such as motor control centers (MCC), transformer cabinets, and capacitor compensation cabinets in factory workshops, protect critical production equipment from faults and reduce downtime losses.

Commercial and civil buildings, such as large shopping malls, office buildings, and data centers, use power distribution systems to ensure stable power supply for important loads such as air conditioning, lighting, and IT equipment, avoiding business interruptions caused by power outages.

Power distribution network: such as 10kV/0.4kV lines, ring main units, and box type substations in urban distribution networks, serving as line protection and monitoring nodes to enhance the reliability and operational efficiency of the distribution network.

Renewable energy access: Adapt to the grid connection protection of distributed photovoltaics and small-scale wind power, prevent the impact of new energy generation fluctuations on the power grid, and ensure grid connection safety (such as overvoltage and overclocking protection).

Customer Value and Service Support

1. Customer core revenue

Improving reliability: By using multi-level protection and rapid fault removal, the equipment damage rate is reduced and the duration of power outages is reduced (such as fault removal time ≤ 50ms, which is much faster than traditional relay protection).

Reduce operation and maintenance costs: remote monitoring and diagnostic functions reduce the frequency of on-site inspections; Fault recording and event recording simplify fault analysis and shorten fault handling time.

Flexible Expansion: Supports seamless integration with other power automation products from GE Grid Solutions, such as SCADA systems and distribution management platforms, to meet customers' upgrade needs from single point protection to system intelligence.

2. Service and Support

The brochure mentions that GE provides full lifecycle services, including:

Selection support: Provide customized selection suggestions based on the customer's equipment type (such as transformer capacity, motor power) and power grid topology (such as radiation network, ring network).

Installation and debugging: Provide technical manuals, on-site debugging guidance (or paid on-site services) to ensure that the product is correctly integrated into the system.

After sales maintenance: Provide spare parts supply, software upgrades (such as protection algorithm updates), fault repairs, and other services to ensure the long-term stable operation of the product.

Product series and selection tips

Model subdivision: The 369 series includes different sub models (such as 369-P, 369-M, 369-C), focusing on "line protection", "motor protection", and "capacitor protection" respectively. Customers need to choose the corresponding sub model according to the type of protected equipment.

Configuration options: Some functions (such as redundant power supply, IEC 61850 communication, temperature acquisition module) are optional configurations, and customers can flexibly customize according to their actual needs (such as whether they need to connect to the smart grid platform).
