Powerful
The TOR 300 platform allows reliable protection, automation and control of MV, HV, EHV and UHV power systems, to combine main and backup protection functionality in a single device. It also provides a lot of additional functions, such as fault location, remote and local breaker control, LED signaling, disturbance and event recording, non-commercial energy measuring, and so on.
Flexible
Each TOR 300 device is freely programmable. Functional logical diagrams have been developed with the use of graphical programming tool allowing for configuration of binary inputs and outputs, analog inputs, control buttons, LEDs, disturbance recorder, event recorder, user interface. Freely programmable logic makes it possible to modify typical functional logical diagrams considering a peculiar nature of the protected object. Four basic types of standard 19" case allow the user to choose the most appropriate solution.
Undemanding
The IEDs can be applied on substations with AC, rectified AC and DC auxiliary voltage. Operating auxiliary voltage range is between 88 … 242 V of DC, 50 Hz or 60 Hz AC selectable by the user. Low power consumption, not sensitive to auxiliary power interruptions, wide temperature range from -40 °C to +55 °C - these are some main properties of TOR 300 devices.
Reliable
TOR 300 has built-in internal continuous self-supervision and fault detection functions which, being activated, enable detecting and alarming (input signal, LED indication) internal faults. TOR 300 ensures no false connection of output relay contacts when energizing and/or disconnecting auxiliary power supply source (regardless the duration of power supply interruption). The device enclosure provides high protection degree according to IEC 60529.
Communicative
Implementation of various communication protocols, such as IEC 60870-5-103, IEC 60870-5-104, ModBus-RTU, Modbus-ASCII and IEC 61850-8-1 (MMS, GOOSE), ensures integration of the IED into substation monitoring and automated process control system, as well as provides data changing with other devices. Standard IEC 61850-9-2 allows connection to "digital (low power or non-conventional)” current and voltage transformers as well as to Merging Units. Built-in optical or HF-ports allow for implementing different types of differential or pilot-wire protection types (optical line current differential, HF-carrier aided directional and others).
