Load measurement system

energy

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 : • Mean value load curve over amounts U, I, P, cosϕ • 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, • 1 pole mounting bracket, • 1 measurement or metering unit (or standby board with a terminal), • 1 communication module using GSM/GPRS, • 1 set of current-voltage sensors for external application, • 1 sensor connecting beam of a defined length 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 • Without measuring equipment to let the user manage the supply to measurement and metering devices separately. 3 versions are available:
