This highly intense Hands-On 3-day or 4-day course provides an in depth Real-World experience of Air Pressure and Leak Locating with a Hands-On Lab environment, giving students a Real-World experience using the pneumatic training simulator...
Equipment Simulator Description The simulator represents both dual and single source feeds. There are four (4) miles of underground cable fed with air pipe, which has four manifolds. Therefore, there are four (4) pneumatic sections dual feed. There are also a number of single feed pneumatic sections in aerial and buried sections. This consists of another eight (8) miles of single source cable. The air source is supplied by a dryer feeding both air pipe and distribution panels.
Students use the hands on simulator as a leak locating tool, using the graphing procedures taught as well as six (6) leak locating formulas. The students use the graph footages and compare with leak locating formulas. This gives the student an appreciation of all leak locating procedures and it will then become his or her decision as to which is best used in the field application.
Optional 4th day (Hands-On in the Field)
There is an optional fourth day. If selected, the class moves from the classroom into the field for helium leak locating and actual hands on work. Thus using the knowledge learned in the last three days in a Real-World atmosphere. If the fourth day is selected then a portion of the third afternoon will be used to set up a predetermined central office to perform helium leak locating exercises. The fourth day is a plus since you have the opportunity to purify a selected central office vault. This consists of checking each cable from the tip or vault splice to where the cables leave the vault. When completed the technician will know whether any plugs are leaking through the core or to the atmosphere and if they should or should not be replaced by using the Calculating Air Flow Formula. Also, if leaks were detected in the sheath (insulating joints or 38 tubing attachment or other damage repairs) they will be located. Any leaks found will be tagged or recorded for technicians to repair at a later date.
