2.2 Environmental Inspection<br />
The environment, where the busducts are installed, sometimes changes after the installation works. Check whether the<br />
environment has become hazardous due to water, moisture, high temperature, corrosive gas, immoderate vibration, dust, etc.<br />
2.3 Inspection for Abnormal Heat<br />
A high-tech Infra Red Thermography instrument is recommended to detect abnormal heat and measure the operating<br />
temperature of busduct system.<br />
For the ease of maintenance, a thermal indicator can be placed onto the busduct housing. If the temperature rise of the busduct<br />
housing exceeds the limit, the colour of the indicator will change. e.g. from white to red colour.<br />
2.4 Inspection on Connection Sections<br />
Check whether :-<br />
HP-Busduct is securely fastened with joint bolts and nuts and both sides of the busduct joint sections are held<br />
with a pair of leaf springs. Leaf springs are flat and the pin holes are inserted with snap pins<br />
Screws and nuts at the overlapping conductor of L-Duct joint sections are not loose due to thermal expansion<br />
and contraction<br />
Busduct is supported by vertical spring hangers, vertical hangers, edgewise / flatwise horizontal hangers according to<br />
manufacturer’s requirement and recommendation.<br />
All the connecting parts, such as leaf springs, hangers, busduct joints, joint covers, etc are fixed precisely<br />
2.5 Inspection on Load Condition<br />
After the installation of plug-in busduct feeders, increase of electrical load is expected at the early stage. An inspection has to<br />
be carried out to ensure that the total connected load does not exceed the rated current of the busduct before the load is<br />
increased.<br />
2.6 Measurement of Insulation Resistance<br />
Measure the insulation resistance between each conductor and between conductor and housing. When it is less than 5MΩ or far<br />
below the previous value, the possibility of existence of defect is very high. When the measurement is carried out, the electrical<br />
loads and connected equipment shall be disconnected.<br />
2.7 Inspection on Rust or Peeling of Paint on Busduct Housing<br />
If there are some peeled-off paint or rust on the busduct housing, cleaning work and touch-up painting are recommended.<br />
