Long Haul Submarine Cable Test Set Model 5903

The Tinsley 5903 Long Haul Submarine Cable Test Set brings the latest technology to the tried and tested DC methods of cable fault location for both repeatered and un-repeatered systems.

The more common test procedures which are associated with the location of types of cable fault such as “open circuits” and “shunt faults” are preprogrammed into the instrument. This allows the procedure to be carried out automatically therefore eliminating operator errors and reducing the uncertainty of the predicted fault position. The instrument may be set for a wide range of voltage and current limits making it suitable for use with most submarine communication cable systems. Safety being an important feature, the instrument gives a continuous indication of the state of charge of the cable under test and will automatically disallow current, voltage or polarity changes to be made until any voltage on the cable has fallen to a level which is safe for both the cable and the instrument. To ensure complete operator safety a number of interlocks operate disconnecting all power before access is allowed to the high voltage areas. The setting up of the instrument is via the menu driven touch screen display. This display is also used to indicate the progress of a test procedure during its implementation. The Ethernet interface is designed for high speed full duplex communication between modules. All functions may also be controlled via a computer and data obtained may be stored for future analysis. This interface may also be used to enable two 5903’s to be connected to communicate with each other when carrying out double ended tests such as “no loss of current”.

Portable Short-Haul Submarine Cable Test Set Model 5910

The Tinsley 5910 is a portable Short Haul Submarine Cable Test Set that brings the latest technology to the tried and tested DC methods of cable fault location.

Common test procedures which are associated with the location of cable fault such as “open circuits” and “shunt faults” are pre-programmed into the instrument. This allows the procedure to be carried out automatically therefore eliminating operator errors and reducing the uncertainty of fault position prediction.

The instrument may be set for a range of voltages and currents making it suitable for use with most un-repeatered submarine communication cable systems.

The RS232 interface is designed for full duplex communication with the instrument. All functions may be controlled via a computer and obtained data may be stored for future analysis. This interface may also be used to enable two 5910’s to communicate with each other via a computer when carrying out double ended tests such as “no loss of current”.

A basic electroding generator function is included which can assist the cable repair vessel in locating the cable on the sea bed prior to retrieval and repair.

Short Haul Submarine Cable Test Set Model 5910R (Rack Mount)

The Tinsley 5910R is a rack mount version of the 5910 portable Short Haul Submarine Cable Test Set. It brings the latest technology to the tried and tested DC methods of cable fault location.

Common test procedures which are associated with the location of cable fault such as “open circuits” and “shunt faults” are pre-programmed into the instrument.

Electroding Generator Model 5915

The Tinsley Electroding Generator, type 5915, has been developed with British Telecom to locate Submarine Telephone Cables. The method employed is the well established electroding technique. The unit is self-contained, desk top mounting, enabling tests to be carried out without the power feed connected to the cable under test.

The 5915 Tinsley Electroding Generator is intended as an aid to cable repair ships in locating and identifying telephone cables. The Electroding Generator energises the Submarine Cable with a low frequency sine wave signal of up to 500mA at 500 Volts peak to peak. The Electroding Generator is located in the terminal station normally nearest to the fault area and connected to the cable under test by means of two safety probes built-in the instrument.

Electroding Detector Model 5916

The Tinsley 5916 Electroding Detector is the ideal equipment for use on board ship when the electroding method is being employed for the detection of submarine cables buried or laid on the sea bed. This light weight and portable instrument can be mains powered or can operate for several hours from its own internal, rechargeable battery pack. Ideally suited for use with the Tinsley Electroding Generators, the 5916 will also operate with any generator operating in the frequency range 4 to 40Hz.

Beach Probe and Battery Powered Portable Electroding Detector Models 5917 and 5918

The 5917/5918 Electroding Probe and Detector system is a high gain low frequency selective Receiver/Amplifier to detect the electromagnetic field from a submarine cable energised by the Tinsley 5915 Electroding generator or similar.

The 5917 Beach Probe and 5917D Divers Probe are inductive probes suitable for receiving 15 to 30Hz signals emanating from a suitably energised submarine cable.

The 5918 detector amplifies, filters, and indicates the signal received at the selected frequency. At the highest gain setting a 10µV RMS input signal at the correct frequency will give a full scale reading on the analogue front panel meter.

The 5918 electroding detector is completely self-contained in a portable carry case with shoulder strap. Integral rechargeable batteries are included and a separate mains power module is supplied to recharge them.

In use the 5918 detector is connected to the receiving probe, either a Tinsley type 5917 Beach probe or 5917D Divers Probe. The exact operating frequency is selected on the thumbwheel switches and the gain switch is adjusted to obtain a useful indication of the signal. A frequency of either 16.7Hz or 25Hz is recommended when using the 5917 Probes.

An audible output signal is available which can be heard by using the plug in headphones supplied. The larger the signal received the higher the frequency heard. A volume control is provided for adjustment of loudness.

Cable Termination Unit Type 5941

The Tinsley 5941 CTU is the ideal termination unit for non-repeatered submarine cables. It offers a simple method of selecting an open or short circuit condition and a safe means of discharging the cable. The unit is designed to enable the Test Engineer to safely and simply connect other Tinsley test instruments to the system for fault location and electroding.

The Tinsley 5941 CTU also incorporates a Cable Condition Monitor. Any changes in the Submarine Cable electrical characteristics are automatically detected and an alarm is triggered. An output from the alarm is also available for connection to outside devices.

5941TERMThe unit can be connected to the cable via a dedicated cable connected to the fibre optic cable metallic conductor. Alternatively, the fibre optic cable can be routed into the CTU with a direct path through the unit for the optical fibres. Options that can be set at the time of installation enable the unit to be used with a wide range of cable lengths and types.
