LOSSES HOW TO REDUCE THEM AND WHY? KPT-OIPT 013E‚ Published 02.2000. Generally‚ there is a simplified understanding that the socalled load losses in a transformer (load losses‚ PL ) depend on the ohmic resistance of the windings. This is only partly true‚ as the losses arising from magnetic leakage flux in various metal parts of a transformer constitute a significant part of the total losses. This component of total losses is called stray (additional) loss (Ps ). In addition‚ experts distinguish

be assigned a specific operating time and the use of the OPTO-isolator totally isolates the PC from the hardware‚ therefore protecting the parallel port from overloading. Firstly the power supply is built‚ a 240v-15v AC transformer is used‚ the 15v section of the transformer is solder to the vero board and a bridge rectifier is fixed to the wires on the board‚ the filtering capacitor (1000uf) is connected to DC output of the rectifier‚ then a voltage regulator (LM7812) is connected to the output

insulated switchgear (GIS) is ideal for such applications. The range of application of SF₆ Gas Insulated Switchgear extends from voltage ratings of 72.5 kV up to 800 kV with breaking currents of up to 63 kA‚ and in special cases up to 80 kA. Both small transformer substations and large load- centre substations can be designed with GIS technology. The distinctive advantages of SF₆ Gas Insulated Switchgear are: compact‚ low weight‚ high reliability‚ safety against touch contact‚ low maintenance and long life
