  • telby® 20kV Universal Broadband Isolation Transformer up to VDSL2 and G.fast - up to 280 Mbit/s Image
  • Telbit has developed a selection of Universal Broadband Isolation Transformers capable to protect a range of bandwidths suitable for for Voice and Data Transmission from POTS to DSL technologies including HDSL, HDSL2, SDSL, SHDSL, G.SHDSL, ADSL, ADSL2, ADSL2+, G.lite-ADSL, VDSL2 and G.fast from 200 Hz up to 30 MHz with up to 280 Mbit/s.

    The Universal Broadband Isolation Transformer is designed to isolate the incoming telecommunication line from the customer equipment located in a high-voltage environment (HVE). This method provides a physical barrier between the customer equipment and the incoming line, resulting in a fundamental isolation protection (HVI) within hazardous areas (ZOI), such as power generators, substations, heavy power users, lightning prone areas or where soil conditions provide unsuitable earthing conditions leading to Earth Potential Rise (EPR) / Ground Potential Rise (GPR).

    This condition is known to lead to damage not only to customer equipment connected to the incoming copper pair, but also to the Telco providers’ exchange equipment. Possible damage to the copper in the ground and other circuits within the cable bundle is also prone to damage in extreme situations. Any of the above situations can lead to expensive repairs, and time-consuming downtime for all involved.

    The telby Universal Broadband Isolation Transformers are fully passive component and do not require any sort of power supply, resulting in an unmatched reliability.

    The Line Isolation Transformer is to be placed immediately inside the facility at the first telephone equipment panel. Refer to local codes for enclosure requirements.

    For 4-wire connections, two Transformers are required.

     

    Span power option: If necessary, an optional secondary 60 mA DC power feed module for up to 120 VDC can be built-in. This can provide power to the Station side span for span powered Network Communication Telephone Equipment (NCTE). A local power source external to the standalone unit is required for this span power feature.

    Warning: Never install telephone equipment in a wet location or during a lightning storm. When installing or modifying telephone lines, disconnect lines at the network interface before working with uninsulated lines or terminals.

     

    SPECIFICATION / TECHNICAL DATA

    ISOLATION SPECIFICATION
    Longitudinal Surge (1.2/50µs) 100kVAC r.m.s.
    Lightning Surge (8/20µs) 100kVAC r.m.s.
    Continuous Rating (50Hz, 60sec) 20kVAC r.m.s.

     

    Dielectric Strength
    The combined dielectric strength of various dielectric components that make up the insulation of the telby Universal 20kV – Broadband Isolation Transformer is called Basic Impulse Insulation Level or Basic Insulation Level (BIL). This value, usually in kV, indicates the equipment’s ability to withstand overvoltage caused by lightning and switching surges. The BIL voltage is the voltage that the equipment will withstand for the given length of time and the given number of applications without the insulation failing (ie. without an occurrence of flashovers). It is expressed as an impulse peak voltage with a standard wave lasting not longer than 1.2µ rise time and 50µ fall time.

     

    Insulation Breakdown
    Earth Potential Rise (EPR) or Ground Potential Rise (GPR) is a safety issue in the coordination of power and telecommunications services. An EPR/GPR event at a site such as an electrical distribution substation may expose personnel, users or structures to hazardous voltages. Any conducting object connected to the substation earth ground, such systems as telephone wires may be energized at the ground potential in the substation. This transferred potential is a hazard to people and equipment connected to these wires.

    Insulation Transformers used as a High Voltage Interfaces (HVI) must withstand the applied alternating 50/60Hz voltage. The tests performed with alternating voltage are more realistic than the tests performed with D.C. voltage.

    A.C. testing is required for testing of the assembled electrical equipment. The A.C. tests performed on assembled electrical equipment are usually “go/no go” types of tests. If the leakage current indicator does not light up, the equipment passed the test. However, these tests are not a guarantee of future performance, nor any indication of how long the equipment may last in case of Earth Potential Rise (EPR) or Ground Potential Rise (GPR) condition.
