 term or phrase: Napiecie /prad GN lub SN lub DN Kontekst: Podstawowe elementy przylacza Transformatory blokowe elektrowni
 English translation:Voltage / amperage, primary, intermediate, secondary Explanation:NAPIÊCIE = VOLTAGE PR¥D = AMPERAGE / CURRENT GN = GÓRNE NAPIÊCIE = PRIMARY VOLTAGE SN = (PO)ŒREDNIE NAPIÊCIE = INTERMEDIATE VOLTAGE DN = DOLNE NAPIÊCIE = SECONDARY VOLTAGE Transfer of energy in power system is usually done with high voltage lines (110kV, 220kV, or even higher). This reduces current (amperage) and therefore losses. Transformers are used to step down the voltage to medium voltage (15kV, 6kV) for local distribution, and to 0,4kV for end users. The transformer winding operating at the high voltage is called PRIMARY WINDING(GN = GÓRNE NAPIÊCIE) The transformer's winding operating at the low voltage is called SECONDARY WINDING(DN = DOLNE NAPIÊCIE) The transformer may have an intermediate winding operating at the voltage somewhere in between, and is called INTERMEDIATE WINDING(SN = ŒRODKOWE NAPIÊCIE). So a transformer may operate at : 10kv/1kV/0.4kV for an example look at: http://www.muse.navfac.navy.mil/substations.htm Hope it helps, Jacek

Voltage / amperage, primary, intermediate, secondary

Explanation:
NAPIÊCIE = VOLTAGE
PR¥D = AMPERAGE / CURRENT

GN = GÓRNE NAPIÊCIE = PRIMARY VOLTAGE
SN = (PO)ŒREDNIE NAPIÊCIE = INTERMEDIATE VOLTAGE
DN = DOLNE NAPIÊCIE = SECONDARY VOLTAGE

Transfer of energy in power system is usually done with high voltage lines (110kV, 220kV, or even higher). This reduces current (amperage) and therefore losses. Transformers are used to step down the voltage to medium voltage (15kV, 6kV) for local distribution, and to 0,4kV for end users.

The transformer winding operating at the high voltage is called PRIMARY WINDING(GN = GÓRNE NAPIÊCIE)

The transformer's winding operating at the low voltage is called SECONDARY WINDING(DN = DOLNE NAPIÊCIE)

The transformer may have an intermediate winding operating at the voltage somewhere in between, and is called INTERMEDIATE WINDING(SN = ŒRODKOWE NAPIÊCIE).

So a transformer may operate at :
10kv/1kV/0.4kV
