Single-phase TRO
Features of TRO transformers:
- The increased load ability
- High level of isolation of windings
- The shielding winding
- System of restriction of starting current
- Deviation of output tension idling and under loading no more than 5% of the input
- Monitoring system of current and temperature of windings of the transformer
- The monitoring system of isolation of the transformer and the connected network
- Low noisiness
- Natural ventilation
Circuit executions of transformers
- Execution 1. On an entrance and an exit costs on one regular automatic switch
- Execution 2. In coordination with the customer in a secondary chain the additional switching element (protection machine guns) is established
- Execution 3. Allows to realize automatic input of a reserve for one load
- Execution 4. Allows to realize automatic input of a reserve for several loadings
SV – the network supported by the emergency power supply
