Transformer Protection_thumb

Transformer Protection

Transformer protection and maintenance is essential for a reliable energy supply. The intelligent electronic devices from SEG Electronics with perceptive algorithms protect your electrical equipment against damages that are costly and difficult to replace.

The protective relays from SEG Electronics offer a wide range of protection and supervision elements. Integrated recorders and logging functionality assist the user in detecting transformer aging and analyzing failures.

Enhanced communication capabilities are the basis for the integration into automation systems.

 

 

Motor Protection_thumb

Motor Protection

To ensure day-to-day electrical induction motors keep processes running, and to maximize the motor’s operating life, SEG Electronics offers a variety of highly-adaptable Intelligent Electronic Devices to protect them against inadmissible electrical, thermal, or mechanical stress.

 

 

Line Differential Protection_thumb

Line Differential Protection

SEG Electronics offers line differential protection with fiber optic communication, because it is the best way to protect an overheadline or cable. Speed is important for differential protection because it is the most selective protection. Since communication between the devices occurs via fiber optic connections, data transmission is not only especially fast, but also extremely safe.

In addition to complete line protection, the HighPROTEC relays from SEG Electronics offer measuring and control functions and integrated backup protection.

 

 

Generator Protection_thumb

Generator Protection

The Intelligent Generator Protection Relays from SEG Electronics provide a broad scope of primary and backup protective functions, from overcurrent protection to generator differential protection. This highest availability is a key factor for reliable power generation.

 

 

Interconnection / Mains Decoupling_thumb

Interconnection / Mains Decoupling

During mains failures, DER (Distributed Energy Resources) should stay operated and connected to the grid to support decreasing mains voltage, by feeding reactive power. SEG Electronics has developed various Intelligent Electronic Devices, which are in compliance with international grid requirements (Grid Codes), to avoid electrical or mechanical damage to the DER in these cases.

 

 

CT-/Self-Powered Protection_thumb

CT-/Self-Powered Protection

All relays from the WI Line are self-powered time overcurrent relays, which means they take their energy from the current transformers.

Since they do not require auxilliary power, the WI Line relays are well suited for use in self-sustaining transfer and distribution stations, local grids, and ring-main-units.

Tripping characteristics range from two-stage, independent (DEFT) and dependent (INV) time-overcurrent protection, up to special characteristic curves. As further options, we offer some relays with integrated earth fault protection.

SEG Electronics has also developed serial products, which match nearly any circuit breaker commonly available on the market. The electronic parts of the relays are completely sealed in. This makes the relays resistant to even the very worst environmental influences.

Feeder Protection_thumb

Feeder Protection

From the generation via transmission and distribution down to the load, the feeder protection relays from SEG Electronics protect the entire power chain throughout different voltage levels.

Modern communication and linking to systems are the basis for economical and efficient applications of your operating components. For nearly every communication network SEG Electronics offers you various protocols like Modbus® RTU and Modbus® TCP, Profibus® DP, IEC 60870-5-103 and IEC 61850.

The easy-to-use feeder protection relays from SEG Electronics work safely and precisely, and are well-proven in the fields of utilities, industrial, and other power systems. They are thoroughly designed and engineered to maximize the availability of your power distribution system.

 

 

Supervision Devices_thumb

Supervision Devices

SEG Electronics supervision relays for low voltage applications are equipped with a precise micro-controller and designed for DIN-rail mounting. They are easy to operate and simplify commissioning. This is advance technology at low price.
