Case Study | Manufacturing | Afrox Linde | Witbank 33/11kV Transformer T9 Online Assessment
The client provides engineering services and a focused range of performance enhancing Atmospheric Gases, Welding and safety products and LPG to valued customers. Given the criticality of the services offered by the client, transformers in all electrical networks must be kept to a high reliable and maintainable standard to prevent premature failure.
Client Reference | Mining | Mechanical Plant Monitoring
A large, independently operated and managed, black empowered manganese ore producer finds themselves under constant pressure to meet production demands with a single line from crushing to load out for export. A machine failure on the line results in high repair costs and downtime, which imposes significant risk.
To ensure the deliverables are met safely and responsibly, the producer adopted effective maintenance management principles. This decision led to the journey of condition-based maintenance.
Client Reference | Improved MV Substation Reliability and Safety with Condition Monitoring
Our client is an electrical utility responsible for the supply and distribution of bulk electrical power to industrial and residential customers in six administrative regions within their country.
Client Reference | Mining Industry | Seismic Vibration
A large mining client received a number of complaints relating to residential property damage due to mining activities in the area.
Client Reference | Defect Findings of Medium Voltage Type “C” Terminations at Solar Plants
A client working in the renewable energy space approached Martec to provide a condition assessment of around 800 Type “C” terminations in operation at various solar plants in South Africa.
Client Reference | Intime Condition Monitoring for Water Utilities
Martec prevented water outages by providing emergency service to assist a utility when they experienced a breakdown on the switchgear running the pumps.
Case Study | Online condition Assessment Findings of MV Power System (DRUPPS) | Nampak
A failure of the DRUPPS unit 2 reactor led to an investigation and online condition assessment of all the units (1 to 10).
