COMMUNICATING MEASUREMENT OR METERING BOX Provides surveillance and monitoring of an overhead substation. The boxes consist of a pole-mounted transformer and a protective device (fuse-protected panel or circuit breaker). Main features The pole-top measurement or metering box gives LV distribution network operators the ability to access the following information remotely : q q q q q q q q Mean value load curve over amounts U, I, P, cos? Recording and time-stamping of maximums and averages over U,I (maximum demand indicator function) and P Monitoring of voltage thresholds and local transformer balancing Monitoring of loads and load totals on the transformer Metering function (with a daily total of active and reactive energy) Detection of supply interruptions Alarms (on disconnection, on exceeding the threshold, and more)) Communication of alarms or data (GSM module, GPRS, Ethernet link) The most common make-up of the measurement and metering box: Polyester composite enclosure boxes, whose dimensions and shapes vary according to the choice of the measurement device and the user’s expressed needs, q 1 pole mounting bracket, q 1 measurement or metering unit (or standby board with a terminal), q 1 communication module using GSM/GPRS, q 1 set of current-voltage sensors for external application, q 1 sensor connecting beam of a defined length q This equipment can be prepared and configured in various ways : With a pre-connected measurement or metering device that has been factory programmed and calibrated to create a device ready to be installed and commissioned q Without measuring equipment to let the user manage the supply to measurement and metering devices separately. q Monitoring box without measuring or metering equipment (with standby U and I links) Monitoring box with a multi-functional measurement unit

Monitoring box pre-equipped with a three-phase meter Configurable solution according to the customer’s specifications. Powered by TCPDF (www.tcpdf.org) Rural Environments
