![]() The temperature rise can be calculated from the measured resistance value and ambient temperature. Temperature-rise testing can also be performed using resistance measurement. Additionally, like the loading-back method, this method requires temperature correction and other procedures. Note that since the total loss is supplied as the load loss, it's necessary to know the underlying figure in advance. In this method, the temperature rise is measured after shorting one of the transformer’s windings, applying a current to the other winding from a power supply of the rated frequency, and applying the loss equal to the sum of the no-load loss and the load loss. Precautions must be taken since the method requires at least two transformers with the same rating, and measurement results need to be temperature-corrected. Since the supply capacities used in the test are low, the method can also be used to test high-capacity transformers such as those used to supply electric power. In this method, measurements are made while supplying the no-load-loss and load-loss supply capacities individually. Consequently, it is used to test low-capacity transformers. It’s not realistic to use this method when testing high-capacity transformers. This type of temperature-rise test is carried out while the transformer operates under the rated load. The following three measurement methods are used: Actual load method In such testing, the temperature of components such as the transformer’s oil or winding is measured. Temperature-rise testing is used to determine whether a transformer’s temperature rises behind the specifications value when operating under rated conditions.

The inverter part of the unit still works. There is evidence of a lot of shoddy work in the manufacture of this RV. I just don't want to do any damage to the wiring in the process of removing the charging part. They just start out with pull out the unit. I have excellent instructions on how to install the new charging part of the unit. ![]() I was hoping that someone may know if Safari would have used long enough cables to pull it all of the way out.Īs for the charging unit itself I have purchased an upgraded unit with modern electronics was well as three way charging to change and maintain batteries that has fast charge, slow charge, and trickle charging which is supposed to be able to maintain the batteries in winter and is supposed to create a situation where you only have to check the batteries every three months. It comes out about five inches and then stops. It appears that the only way to remove the unit is to pull it straight out. The cabinet above has permanently attached shelves. The unit is completely surrounded by cabinets which are solid and provide no access. There ought to be some access, but so far I haven't found it. If you have any answers please let me know. The furnace is to the left, and drawers are to the right. I can't figure out how to get to the back of the unit. Has anyone had to pull one of these out? Can I assume that there is enough wire behind it that I can pull it all of the way out? Right now I can only move it about four inches. ![]() I know that Safari got rather haphazard in the time period when ours was made. Has anyone here replaced the lower unit of one of these MagneTek power converters? So after more than two weeks with FedEx it finally has arrived. So reading upon this I found out that MagneTek is now Parallax and they still make replacement parts for this unit as they were put in many if not most Rvs in the 90s. Now the unit won't charge my new batteries and I have no 12v power unless I'm hooked up to a land line. It ended up frying my batteries, and the power converter a MagneTek 6345 got so hot that the fan ran until it died. So I broke my hip last winter and my RV sat all winter plugged in. ![]()
