$ u& y- U, I5 _8 wConsidering sub-clause 30.2 of part 1 including A2, how shall the glow wire test on motor capacitors be performed and on what parts?
Photo 1 shows a resin embedded motor capacitor where the internal connection between the wire and the plate is a soldered.
9 D- I% ]3 J2 qPhotos 2 and 3 show the points of connection on the upper and lower part.
) ]( n; F+ ]5 K* t9 QIn all the figures, the connections are within 3 mm of the external plastic case of the capacitor.
& P1 i; S' z: X5 t9 U. I0 @Decision:
The glow wire test has to be performed over the shielding and shielded materials joined together, at the point the connection is made, at 750°C, from the inside to outside as normal testing, allowing the tip to penetrate the shielded material. In this case, the shielded material is the external plastic case because it is within 3mm from the connection (as in the figures).
