    2: Hardwired (4kVA Upwards including Three Phase UPS) – Maintenance Contracts

    No matter what, your UPS, Generator, Cooling, Switchgear or Electrical Hardware must be ready to perform at all times. While every power solution we supply is backed-up by a comprehensive warranty with the manufacturer, maintenance plans to ensure business continuity are highly recommended, particularly for UPS systems from 4kVA. In particular, the battery set is of prime importance, and must be in good working order. With other consumables, such as fans and DC capacitors requiring regular maintenance and inspection logs reviewed to predict potential future problems.

    4. IR Thermal Imaging Surveys – Infrared electrical inspection. Infrared electrical testing finds hot, dangerous problems quickly. Infrared electrical inspections find hot spots caused by defects in connections and components. – Contact us for more information.

    Detect system overloads, loose defective components and damaged switchgear. Infrared electrical testing finds hot, dangerous problems quickly. Infrared electrical inspections find hot spots caused by defects in connections and components.

    Infrared thermography is used to find areas of excess heat (caused by increased resistance) so that problems can be corrected before a component fails, causing damage to the component, creating safety hazards and productivity loss. Because increased heating is a sign of failure, infrared is the best diagnostic tool available for finding these hot connections in the early stages of degeneration.

    5. Switchgear – Contact us for more information.

    Switchgear maintenance is essential for efficient save plant operation and prolonged life span in the field Switchgear should be maintained as follows.

    • Live Maintenance – Unintrusive and consists of taking metering values, carrying out visual inspections and a thermal imaging survey of the switchboard. This is recommended to be carried out yearly.
    • Breaker Maintenance – Switchboard would need to be Isolated and all ACB’s and MCCB’s are maintained including visual and mechanical checks, greasing and secondary injection testing of the trip units. This is recommended to be carried out every 2 years.
    • Full Isolated Maintenance – Switchboard would need to be fully isolated from upstream supplies (HV). Breakers are maintained as per the above but also full maintenance carried out of the Switchboard to clean all compartments and carry out tightness checking of busbars and terminations etc. This is recommended to be carried out every 4 years.
