The REG216 software system provides a library of protection functions. The following table lists the functions applicable to generator and transformer protection.

Different levels of redundancy can be selected.

The availability and reliability of the protection can be selected according to the application in the following ways

For example, the auxiliary power supply unit for the entire system can be replicated.

Standard interfaces make the REG216 compatible with different process control systems.

Construction

Hardware

The REG216 device consists of two main components, which are physically separated from each other and connected by standard prefabricated shielded cables

Connected by standard prefabricated shielded cables:

– The main system interface (CT, PT and auxiliary relays), which provides DC isolation and EMI barriers.

Isolation and EMI barrier

– Parallel bus and associated electronic units (e.g. analog inputs and data processors / for signal conditioning and processing).

The complete protection scheme consists of a relatively small number of hardware modules, allowing subsequent expansion of the electronic units and interfaces. Each device frame provides 21 rack spaces.

All hardware can be housed in a single compartment, which provides further shielding against inductive interference and physical protection against dust, etc.

All hardware can be accommodated in a single compartment, which provides further shielding from inductive interference and physical protection from dust.

The REG216 is available in 17 predefined rack configurations with a limited number of I/Os, but is equipped with the same SW library as the classic system.

Protective relays for other functions are not part of the EG216 and can be installed in compartments and interconnected with the REG216 accordingly.

Interfaces to the main system

The following modular components provide the interface between the REG216 and the power system.

Product overview

3.1 Purpose of the relay

The feeder protection relay REF610 is a multifunctional protection relay primarily used to protect incoming and outgoing lines in various feeder applications.

The relay is based on a microprocessor environment. A self-monitoring system continuously monitors the operation of the relay.

The human-machine interface includes a liquid crystal display (LCD) that makes local use of the relay safe and easy.

The relays can be controlled locally via serial communications from a computer connected to the front communication port.

Remote control is available through a serial communications bus connected to the rear connector of the control and monitoring system.
