Transformer Monitor Functions as a Data Concentrator
The Transformer Advantage can interface legacy transformer sensors to substation networks and alarm systems. The new Analog/Digital Input function accepts up to eight external AC, DC, switch or logic inputs. The output from a sudden pressure switch, low oil detector, tap position sensor or other transformer gauge can now be monitored by the Weschler unit, along with oil, winding and LTC temperatures. The Transformer Advantage also links these external devices to control relays and alarms, with adjustable high and low limits for each channel.
With the Transformer Advantage, utilities can remotely monitor transformer gauges and sensors through their substation network. Linking these devices through the Transformer Advantage is more cost effective than interfacing each device directly to the network. It is also particularly useful for older gauges that lack a digital communication capability. Connection can be through a twisted pair cable or optical fiber. Both ASCII and DNP3.0 protocols are supported.
The Analog/Digital Input option can be utilized on new or installed transformers. It is available on all Weschler Advantage models. More info
