JSZW-10WF FIVE LEG TYPE OUTDOOR THREE PHASE VOLTAGE TRANSFORMER FOR CIRCUIT BREAKER
The type JSZW-10WF Outdoor three phase voltage transformer is single phase and epoxy resin silicon rubber insulated product, it's used for metering electric energy, voltage control and relay protection in 50/60HZ rated voltage 10kV electric system; and also it can be used for medial voltage AIS, or can be used for medial voltage switchgears. They can operate in all kinds of environments (such as wide range temperature (-50~70℃), high altitude, high humidity, high pollution or salt).
Medium Voltage Product Outdoor voltage transformers Description ... conﬁguration in a three-phase system. one terminal of each secondary winding and one of the open-delta connected terminals must be earthed during the transformer operation.- ... Voltage transformers: Outdoor
V L is the line-to-line voltage, and V P is the phase-to-neutral voltage. A transformer can not act as a phase changing device and change single-phase into three-phase or three-phase into single phase. To make the transformer connections compatible with three-phase supplies we need to connect them together in a particular way to form a Three Phase Transformer Configuration.
