Frequently Asked Questions
Everything you need to know about power plant electronics repair with Synchronics.
Yes. GE Mark VIe and VIeS turbine control boards are one of our core competencies. We repair IS200/IS215/IS400 series processor cards, I/O boards, IONET communication modules, and EX2100e excitation system cards. All repairs are tested on dedicated test rigs that simulate turbine control signal environments before return.
Yes. We repair ABB REF615, REF630, REX640, and Siemens SIPROTEC 5 and 7 series relay boards at the component level. This includes CPU boards, binary I/O modules, CT/VT measurement cards, communication interface boards (IEC 61850, Modbus), and power supply modules. Significantly faster and more economical than OEM replacement.
Yes. We repair Ovation OCR400, OCR1100, and OCR160 controller cards, as well as Ovation I/O modules (analog, digital, thermocouple, RTD). Our test procedures validate controller functionality including processor operation, memory integrity, I/O channel accuracy, and Ethernet communication before return.
Most controller boards, relay modules, and drive cards are returned within 48-72 hours of receipt. For critical generation or grid equipment, we offer emergency priority service with accelerated turnaround. OEM replacement from Europe or the US typically takes 12-20 weeks — our component-level repair is significantly faster.
Yes. We serve thermal, gas, hydro, and captive power plants across all major locations — NTPC sites, state gencos, independent power producers, and industrial captive plants. Courier pickup from Mumbai, Delhi NCR, Chennai, Vizag, Korba, Neyveli, Ramagundam, Mundra, Ahmedabad, and Bengaluru. Pan-India logistics with packing guidance provided.
