Cable-friendly burning
ETF 3
Cable-friendly burning for pilot and
tele-communication cables
The ETF (Energy Separation Filter) 3 kV was specially devel-
oped to perform fault location on symmetrical communica-
tion and pilot cables. The combination of a burn unit, ETF
3 and Teleex allows an operator to quickly perform fault
prelocation on high resistive and humid cable faults. Where
many other measuring technologies fail, the ETF 3 even al-
lows humid faults to be prelocated safely.
The ETF 3 provides a solution for applications where the per-
mitted voltage is limited – by cable type or allowed test volt-
age level – to a level that prevents the use of the standard
burn and fault location technology.
The burn procedure can be directly observed on the dis-
play of the connected Teleflex. The moment the fault breaks
down, the fault distance becomes visible. This permits a
“cable-friendly” limitation of the burn time to the required
duration.
For safety reasons, the input of the ETF 3 voltage is auto-
matically limited to 3 kV by an internal arc gap because the
ETF 3 and any connected communication and pilot cables
have limited permittable voltage levels.
■Direct control of the burning process by
life monitoring
■Highly cable-friendly burn process
■Specially adapted to the requirements of
telecom and pilot cables
■Capable of locating humidity faults
DESCRIPTION
Exceeding these permitted values will have far reaching
negative consequences. Using the ETF 3 requires the utmost
caution and observation of these values.
Combinations are available in the following variations (in or-
der of performance):
Reflectometer with burn unit
Analogue Teleflex T 22/13 B 5 kV mode
Teleflex MX BT 500 IS-1
Teleflex T 30E MMG 10 in 1 kV mode
Teleflex SX works with all burn units
Telefelx VX works with all burn units
