The Sensus Distribution Automation TC032 MicroRTU is a cost effective solution for monitoring and controlling fixed or switched capacitor banks. The TC032 integrates the Sensus FlexNet two-way radio module for communications over the IP-enabled Sensus FlexNet private radio network. Units can be monitored and controlled from central Volt/Var applications or utility SCADA systems through the Sensus SCADA-Xchange application. Engineers, planners, and field technicians can simultaneously check status and configure the TC032 MicroRTU using the Sensus AutomationControl application suite.
The units are ideally suited for smart grid distribution automation applications such as Volt-Var optimization or central control applications for switched capacitor banks.
Models with FlexNet radios communicate using packet data over Sensus FlexNet private networks. The units can be installed on any FlexNet system that is configured to support the AutomationControl application platform.
FlexNet enabled models incorporate all of the standard system security features. Units can be monitored and controlled from central Volt/Var applications or utility SCADA systems through SCADA-Xchange using DNP3/ IEEE 1815 or IEC 60870-5- 101/105 protocols. Engineers, planners, and field technicians can simultaneously check status using AutomationControl applications.
Features and Benefits
Includes local voltage and temperature switching strategiesSCADA override of local strategies Provides capacitor bank control through two 30 Amp relays. After a switching operation, the acknowledgement report includes the AC line voltage, open/close status and the capacitor bank neutral current. Capacitor bank neutral current is measured with a 0-100A current sensor. A neutral current of zero indicates that the installation is switched out of service. Normal neutral current (a nominal value above zero) when the bank is closed indicates the bank is in service and the installation is operating as expected. A neutral current that is higher than average, but below a predefined limit, indicates the presence of high harmonic current or abnormal conditions, which may indicate a potential problem. A higher, pre-defined level of current indicates a blown fuse or other serious problem. Neutral current alarm retry capabilityEasily accessible local/remote switch disables remote operation; the position of the switch is reported when changed Local control delay gives operators time to move a safe distance from the equipment before the capacitor bank is switched Pending operation indication warns operators of any pending bank switching operations An Amphenol connector allows easy neutral current sensor installation Reports under and over voltage conditions, as well as momentary and continuing power outages Includes AutomationControl applications to provide monitoring, control and configuration options. The AutomationControl applications can be used simultaneously with SCADA-Xchange. All setpoints and operating parameters are user programmable from remote locations using a standard PC browser through the AutomationControl application.
