Areas of application

The REG216 is used to protect generators and transformers.

The modular hardware and software design allows extremely flexible installation.

The combination of software libraries and hardware allows simple adaptation to the size of the primary system and the required protection scheme.

The combination of software libraries and hardware modules allows easy adaptation to the size of the primary system and the required protection scheme.

Modules. As a result, economical solutions can be realized in a wide range of applications.

Economical solution.

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.

Data can be exchanged with higher process control levels, e.g. for one-way reporting of digital status and events, measured values and protection parameters.

The REG216 and REG216 Classic differ in their binary process connection:

– The REG216 uses the E/A module 216GD61a.

– REG216 Classic uses modules 216GE61 / 216GA61 and 216GA62.

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.

Input transformer assembly

216GW62 This assembly is used to adjust the signal level and to isolate the primary system CT and PT circuits from the electronic circuits of the protective devices.

One PT and two CTs are available to meet different accuracy and dynamic performance requirements.

Up to 12 transformers can be accommodated, selected according to application requirements. Up to four components, i.e. 48 inputs, can be used.

Auxiliary relay and optocoupler assembly 216GD61a

This assembly is for use with the REG216 version. It provides eight trip relays,

Each relay has powerful potential-free trip contacts (with surge circuit), 16 auxiliary relays and 16 optocouplers.

relays and 16 optocoupler input circuits. Up to four assemblies are available.

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.

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.

* three optional signal output contacts SO3. SO4 and SO5

Switch group SGR1…. .8 is used to route internal signals from the protection stage, external trip signals and signals from the automatic reclosing function to the required signal or power output contacts.

The minimum pulse length can be configured as 40 or 80 ms and the power output contacts can be configured as latching.

Trouble Logger

The relay has a built-in disturbance logger that records the instantaneous measured value or the RMS curve of the measured signal.

and up to eight user-selectable digital signals: digital input signals and internal signals from the protection stage.

Any digital signal can be set to trigger the recorder on the falling or rising edge.
