This tender seeks the design, manufacture, and installation of an online vibration monitoring system for oil-filled high voltage reactors. The solution must include training, spare parts, and ensure compliance with industry standards.
The National Transmission Company South Africa (NTCSA) is inviting tenders for the development of an online vibration monitoring system specifically tailored for oil-filled high voltage (HV) reactors. The scope of work includes the design, manufacture, testing, supply, delivery, installation, and commissioning of the system, which must provide continuous, real-time monitoring of reactor vibrations. This system aims to enhance asset management by enabling early fault detection and predictive maintenance, thereby reducing operational risks and maintenance costs associated with unexpected reactor failures.
Key requirements for the system include the ability to measure vibration displacement amplitudes up to 500 µm peak-to-peak, compliance with cybersecurity standards, and the provision of ongoing technical support for at least five years post-commissioning. The system must operate optimally in challenging environmental conditions, including high humidity and temperature variations, and must be housed in an ingress protection (IP) rated enclosure to ensure durability. Training for engineering personnel on system operation and maintenance is also a critical component of this tender, ensuring that NTCSA staff can effectively utilize the new technology.
This tender is suitable for engineering firms, manufacturers of monitoring systems, and companies specializing in high voltage electrical equipment. Businesses with experience in vibration analysis and asset management solutions are particularly encouraged to apply.
