PREMO
BLOCKING FILTER SOLUTIONS
PREMO Group is introducing a new generation
of blocking filters for smart grid applications. The
innovative PREMO BF Series allows a proper and
more reliable PLC Communication.
The Challenge:
All the European utility companies are changing Old Electricity
meters to Smart meters which works by PLC systems using low
frequency signals, such as PRIME (42-89Khz), G3 (35-91Khz) &
CENELEC Band A (9-95Khz). The noise is coming from the end-user
equipments via household wiring which is too close to PLC frequency
ranges. It blocks the communication between Smart meters and
Concentrators.
The Solution:
PREMO
of attenuation level for reducing all kind of noise from the end user
equipments. The BF-xx-MM, SP, SG3 models are designed especially
for smart meters with Re-connection mechanism which has auto
connect / disconnect based on load impedance.
BF Series Key Advantages:
VERY HIGH PERFORMANCE > 40DB ATTENUATION
HIGH PERFORMANCE > 30DB ATTENUATION
GENERAL TYPE > 20DB ATTENUATION
EASY TO INSTALL INTO THE 220VAC TO 250VAC
50HZ/60HZ NETWORK
DESIGNED WITH 40A, 60A, 80A AND OTHER
CURRENTS OF 7A, 16A AVAILABLE ON CUSTOM

PREMO is the First Company
who comply and listed with
Norms of UNE 207010:2018
Application of the barcode for
coding the equipment related to
the measurement of energy
electric by UNESA (Spanish
Association of the Electrical
Industry).
Note: PREMO BF Series is developed with IP30 to fit inside of
meter cabinets.
In this case, cabinet has better Ingress Protection (IP54 to
IP67), so filter is not necessary to have better ingress
protection. This avoids high cost for the filter.
