Thermographic Survey's

Today's requirement for an effective design & maintenance plan has never been so critical due to increasing pressure by the consumer for the perfect operation of power to provide maximum efficiency.

Thermal Imaging is a technique used to detect any type of fault without interruption to supply system. Thermal camera emits infra-red rays and builds an image of the heat dissipation of the component being analysed. The Camera stores the image on Magnetic Medium which is then transferred to a computer where specialist software identifies the need for corrective maintenance. Thermal Imaging not only detects high temperatures but can also be used to detect temperatures which have fallen below recommended levels, thus providing a wide range of functions for a wide range of equipment, covering small relays to heavy current busbar, transformers and cables etc

Electrical unbalance can be caused by several different sources: a power delivery problem, low voltage on one leg, or an insulation resistance breakdown inside the motor windings. Even a small voltage unbalance can cause connections to deteriorate, reducing the amount of voltage supplied, while motors and other loads will draw excessive current, deliver lower torque (with associated mechanical stress), and fail sooner. A severe unbalance can blow a fuse, reducing operations down to a single phase. Meanwhile, the unbalanced current will return on the neutral, causing the utility to fine the facility for peak power usage.
