We are offering sub harmonic protection relay. S-pro 4000 is a digital, microprocessor-based sub-harmonic protection system that provides comprehensive sub-harmonic protection for transmission lines at any voltage level, particularly those with serial compensation and interconnected with wind farms. Use the s-pro sub-harmonic protection relay for monitoring and protection of uncontrolled sub-harmonics, ensuring a reliable operation of the power grid.

iSIS  is now the switchgear (up to 40.5 kV) with the smallest foot print in the world, reducing the foot print to 50% of GIS switchgear. ISIS is also the greenest switchgear as the insulation is provided by patented solid insulation technology and as such eliminates completely the use of green house gas of SF6. It has other patented features like phase segregated, independantly earthed and metal clad poles, and all active components are insulated with special patented epoxy material, making iSIS extremely safe from fire, explosion and water. Thus, iSIS will be an ideal replacement for the GIS around the world, in all applications where space is critical like in large metropolitan cities, windmill applications, offshore platforms etc. where safety is paramount like in oil, petrochemical, chemical and pharmaceutical industries and in all countries which are increasingly banning the use of SF6 gas in switchgear.

S-PRO 4000  is a digital, microprocessor-based sub-harmonic protection system that provides comprehensive sub-harmonic protection for transmission lines at any voltage level, particularly those with serial compensation and interconnected with wind farms. Use the S-PRO Sub-Harmonic Protection Relay for monitoring and protection of uncontrolled sub-harmonics, ensuring a reliable operation of the power grid. Undamped sub-harmonic current oscillations created by series capacitors interacting with the wind system can cause serious damage to wind turbine controllers and also to conventional generators. The wind turbine's own mechanical system interactions (tower-to-blade) can also generate sub-harmonics, which are detrimental to induction generators, transformers, and may cause resonance at the point of common coupling in the electrical grid. The S-PRO 4000 relay detects these sub harmonic oscillations and allows the utility to monitor and protect the power system by isolating the healthy grid from sub-harmonic generation sources.   Protect against sustained sub-harmonics in wind farm operations Undamped sub-harmonic current oscillations created by series capacitors interacting with the wind system can cause serious damage to wind turbine controllers and also to conventional generators.

We are offering bus protection relay. B-pro 8700 provides bus and substation differential protection (low impedance) with ct saturation security, integrated breaker failure and overcurrent protection with, dfr quality fault oscillography and dynamic swing recording, sequence of events logging, scada control and metering in a fully integrated protective relay solution.

TESLA 4000  is an intelligent, state of the art, user-friendly multi-timeframe dynamic power system recorder with advanced Phasor Measurement Unit (PMU) and Continuous Disturbance Recording (CDR) capabilities. TESLA 4000 is an easy-to-use and cost effective, state of the art, multi-time frame (simultaneous) power system monitoring recorder. The integrated Phasor Measurement Unit (PMU) functionality streams synchrophasor data for wide area monitoring. The TESLA creates records simultaneously in three time domains - fault (fast), dynamic swing (slow) and trend records and also creates event logs. The CDR creates continuous records without triggers which together with the fault, swing and trend records provides wide area visibility of system performance. The CDR also creates redundancy in PMU data.With these powerful recording and communication capabilities, the TESLA recording systems provides the most versatile and complete monitoring of power system health. Application To provide early warning for unstable conditions in power system Improve system planning through real-time state estimation Major load centers, generation facilities and transmission interfaces Easy-to-use settings and analysis software PMU per IEEE C37.118-2005 standard Advanced communication protocols SCADA support with DNP3 and Modbus CDR meets NERC PRC-002 DME standards Remote input modules save on costly wiring runs Lossless data compression for fast file transfer Non-volatile on board flash memory
