________________Interpark Industrial Park

In the month of June we delivered a "Medium Voltage Switching and Breaking Substations" with protection grade IP 54 (outdoor installation) for the Interpark Industrial Park complex, which has one of the best locations for the industrial sector within the Bogota plateau, which includes not only the west of the city, but also the municipalities of Cota, Tenjo, Funza and Mosquera. These projects will consolidate the sector as a large industrial zone and warehouse facility.

These projects will consolidate the sector as a large industrial zone and warehouse facility. The medium voltage switching substation was designed to house Ormazabal cubicles with 24 and 36 KV voltages and currents up to 2500 amperes, as well as different configurations, including circuit breaker cubicles, line cubicles, fuse protection cubicles and metering cubicles. It can also house all the substation's protection and communication equipment. Some of the main components and characteristics of the protection system are.

Integrated Control Unit ekor.rci integrated in the cubicle with the following functions:

• •Short-circuit detection between phases from 5 A to 1200 A


• •Directional detection of phase-earth short circuits from 0.5 A to 480 A.


• •Incorporates detection of phase-earth failures.


• •Three phase voltage presence/absence indication.


• •Current measurement of phase and neutral.


• •Voltage measurement.


• •Active and reactive power measurement.


• •Capacitive voltage sensors installed in MV bushings.


• •Circuit breaker supervision and control.


• •Display for adjustment/local consultation.


• •Front RS232 and rear communication port.


• •RS485 ready for remote control.


• •IEC 60870-5-103 communications protocol.
