BIDDLE Cable Route Tracer
Energized Cable Route Tracer

The Biddle Cable Route Tracer is designed to locate, trace and measure the depth of buried energized power cables. The heart of the instrument is a compact, all-steel control box. It is attached to a precision-wound, swivel-mounted detecting coil that operates from three basic positions:

• Horizontal: for maximum deflection over the cable
• Vertical: for a null over the cable
• 45° angle: for a null at a horizontal distance from the cable that is equivalent to the cable depth

The receiver of the locator features a filtering circuit that responds only to the existing electrical energy radiating from the buried cable. The chronic problem of identification in congested areas is eliminated because the receiver is insensitive to telephone lines, gas and water pipes, and steel reinforcing.

AccuTrace® Cable Route Tracer

The AccuTrace Cable Route Tracer consists of a transmitter, which energizes the line with a traceable signal, and a portable receiver, which detects the signal. The transmitter can energize the line either by magnetic induction from a built-in antenna or by direct conductive connection to the metallic line.

Energizing the line conductively provides increased tracing distance and minimizes signal coupling to other lines. Inductive coupling, which does not require a mechanical connection to the line, permits a buried line to be traced without uncovering or de-energizing it.

The transmitter provides a simple LO/HI pushbutton to adjust the transmitted signal's strength, and a PULSE button for battery conservation and easy identification of the signal.

The receiver can be used to trace lines using either peaks (detection of the maximum signal) or nulls (detection of the minimum, or zero, signal).

The antenna is swivel-mounted for operation in vertical, horizontal or 45 mode used to calculate depth. The receiver provides audible and visual indication of detected signal strength. Simple controls adjust sensitivity and amplification, and a jack provides for audio output to an optional headset.

Standard AA batteries provide up to30 hours of continuous operation. When the receiver is not in use, the telescoping handle retracts for convenient, compact storage

BIDDLE Cable Height Meter
Cable Height Meter

The Biddle CHM Series of Cable Height Meters utilize ultrasonic sound to determine the height of up to six overhead cables and wires. The instruments are designed to address specific measuring requirements on cables up to 75 feet (23 m). The CHM600 (C/N 659600) and CHM600E (C/N 659600E) are designed primarily for power cable applications, while the CHM2000 is designed for telecommunication applications.

The Cable Height Meters emit short bursts of sound which originate from the cone shaped transmitter. The microprocessor in the instruments calculates the elapsed time for the bursts of sound to be reflected from the cable back to the instruments. The result can be displayed in either feet and inches or meters. However, before the final measurement can be displayed, the air temperature must be measured because the speed of sound varies at approximately 0.2 percent per degree Celsius.

A temperature sensor, mounted at the front of the instruments, senses the actual air temperature. This information is sent to the microprocessor and incorporated into the algorithm. The distance is then displayed in meters or feet and inches depending on which was

Hand-Held Time Domain Reflectometer

The Single Phase TTR, Transformer Turns Ratio Test Set, measures the turns ratio and exciting current of windings in power, potential and current transformers. Deviations in turns ratio readings indicate problems in one or both windings or the magnetic core circuit.

The TTR test set aids in identifying:
• Shorted coils
• Open circuits
• Incorrect connections
• Internal faults or tap-changer defects in step regulators as well as in transformers.

The single phase model is available in either hand-cranked or line-operated versions and measures highly sensitive turns ratios of up to 129.99:1 with accuracy of ±0.1%. An optional auxilary transformer extends the ratio range to 329.99:1.

The TTR set operates on the principle that the voltage ratio of the transformer at no load is practically equal to the true turns ratio.

BIDDLE Three-Phase TTR
Three-Phase Transformer Turns Ratio Test Set

The Biddle Three-Phase Automatic TTR is designed to measure the turns ratio of power, instrument, and distribution transformers in a substation or manufacturing environment. At 16.5 lbs (7.5 kg), it weighs less than any other commercially available instrument. A rugged and robust design makes this TTR well suited for use in a variety of harsh environments. The TTR is also particularly suited for testing in power transformer manufacturing environments where testing of complex, three-phase substation power transformers can be performed quickly while minimizing the possibility of errors.

This new TTR measures the highest turns ratio range in the industry (10,000:1) and also provides the highest accuracy (0.1%). No other instrument's performance is comparable that is commercially available today.
