Substation Automation System
Digitisation of Electrical Substations is the need of the hour as electrical grid networks keep expanding to accommodate new energy sources and increased demand from consumers. Automation of Electrical Substations provides Grid Operators with advanced capabilities such as intelligent network-level load flow calculations, forecasting and remote controlling to ensure a reliable and efficient system. Know More
Controlled Switching Device
Our Experience in understanding the DUT(Reactor or Transformer Breakers) through our T&M Vertical has helped us to bring the Intelligent system to operate the CB on ‘ZERO Crossing’ with the ‘point on Wave Controller’ technology in association with our valuable Collaboration. More than 250+ devices are already in operation in Indian Power Sysytem. Know More
RTU Automation Solution
Apart from substation automation we have solution for SCADA/OMS/DMS/EMS required for state load dispatch centres (SLDC’s) and distribution management system. We have excellent RTU based automation system which is extremely cost effective solution for the conventional s/s to convert them to fully automated substation and make them compatible to smart grid.

Circuit Breaker(CB)are designed to switch On & Off the circuit. Under a fault condition; No sooner it receives the command to Open, It opens the circuit but while doing so the CB goes through tremendous stresses and contact are opened to Arc. All this can be reduced using a Controlled Switching. SCOPE in association with Vizimax, Canada offers a Controlled Switching Device (CSD) for MV/HV/ EHV/UHV Circuit Breakers, SynchroTeq series, is the one and only “Manufacturer Agnostic” solution, applicable to either brand new or existing equipment.
This Point on wave operates with intention to have minimum stress on CB while opening or closing keeping the primary function of the CB to switch the circuit in minimal time and without affecting the Grid.
When SynchroTeq Plus receives a CLOSE command, a time delay is initiated, awaiting the first zero-crossing of the phase A voltage for synchronization of the C/B mechanical operation. Should no zero-crossing be detected within the pre-set time delay, controlled switching is aborted and a three-phase random CLOSE is executed if allowed. Should a zero-crossing occur within the pre-set delay and providing no failures are detected, the SynchroTeq Plus sends controlled CLOSE commands to each phase.
The computed time delays are measured from the reference zero-crossing and the time is adjusted to account for environmental factors, measurement sand variations in the C/B characteristics of each phase.

Applications
- Capacitor Banks
- Shunt Inductors
- Power Transformer
Advantage of using Controlled Switching Device
- Can be used on any technology of circuit breaker
- Can manage the energization of power transformers based on the residual flux
- Advanced C/B timing compensation
- Fast response time
- Huge event/waveform memory capacity (2000 Events)
- Waveforms recordings are COMTRADE compatible
- Simple and secured web interface
- Remote support
- Compatible with IEC 61850, DNP3.0 and MODBUS
The SynchroTeq unit improves the operating conditions of the circuit breaker:
- It reduces the possibilities of re-strike and re-ignition
- It reduces the inrush current and optimize the arcing time, and therefore reduce the contact wear on the circuit breaker
Nothing is worse than random closing: therefore, SynchroTeq improves the situation!
The SynchroTeq unit is 100 times more accurate and repeatable than a typical circuit breaker:
- The SynchroTeq control timing is done using a 10 microsecond resolution
- The SynchroTeq+ alarm detection and feedback measurement is evaluated using a 100 microsecond resolution.
Isn’t a digital electronic system more accurate and repeatable than a mechanical system such as a circuit breaker?
The SynchroTeq unit records the event and waveforms during the opening and closing operations, therefore it is used as a circuit breaker diagnostic tool:
- If something goes wrong with the circuit breaker, alarms are generated
- SynchroTeq records all the alarms an operation, including the waveforms data of the CB operation
