As a TDR - This instrument offers all the established functions of the CFL510E (TDR1000)in a simple low cost hand-held unit capable of fault finding up to 3 kM. A large graphicalLCD display clearly shows the characteristics of the cable being tested.

As a Bridge - An automatic test sequence performs a seamless insulation test, a loop testand a fault test to establish the location of cable faults which are undetectable usingstandard TDR technology. Range capability of the fault test can be up to 100 kMdependent on the coductor diameter and resistance.

As a Voltmeter - Selecting the “Meter” option permits DC voltage measurements. Thesecan be used to establish a range of line-status information such as: hazardous voltages,battery voltage level and line polarity prior to performing other tests. This instrument iscapable of measuring up to ±250 VDC.

improved fault locating• Trace averaging capability to reduce the effect

of intermittent noise• Zoom capability• "TX Null" capability to improve close-in fault location and allow for more

effective fault locating on longer cable runs• 3-year warranty

This TDR is an advanced instrument capable of identifying a wide range of cable faults using TimeDomain Reflectometry. Narrow pulses of electrical energy are transmitted along the cable. Thepulse travels through the cable at a velocity determined by the cable insulation. Changes incharacteristic impedance of the cable will cause the pulse to be reflected which then is displayed onthe instrument.

It can be used on any cable consisting of at least two insulated metallic elements, one of whichmay be the sheath or shield of the cable. Dual inputs and large graphic display allow a wide rangeof comparative tests to be performed between cable pairs or stored traces. It includes a “TX Null”(transmit pulse nulling) feature that enables the operator to eliminate the transmitted pulse fromthe displayed waveform for enhanced fault locating. The instrument has 15 trace memories, whichallow previous test results to be displayed. The included download software allows transfer of thewaveform data to a computer for analysis and storage for future reference.

The advanced features of this TDR make it ideal for the demanding applications of cable testing.

BIDDLE Three-Phase and Single-Phase Transformer Loss Measurement Systems• Optional software for data acquisition

and test reports• Tests distribution transformers• Meets latest revisions of IEEE C57

Transformer Loss Measurement Systems (TLMS) are ideal foruse by transformer manufacturers to perform quality-controltesting, and by repair and rewind shops to identify inefficient,high-loss, older transformers. They also are used by electricutilities as part of a loss evaluation program for new or usedtransformers. These systems are specifically designed fortesting pole-top and pad-mount transformers. The Three-PhaseTLMS tests distribution transformers up to 35 kV class rated upto 2500 kVA three-phase.

PARTIAL DISCHARGE DETECTION SYSTEMS

The BIDDLE® PD/RIV Detection System permits simultaneous measurement of both partial discharge inpicocoulombs, and RIV, in microvolts. Traditionally, RIV has been measured in microvolts using a radio noisemeter, according to NEMA Standard 107. More than 50 years of experience has been accumulated with RIVmeasurements by manufacturers and users of power transformers and power apparatus. The only way tocorrectly correlate picocoulombs and microvolts is to take both sets of data simultaneously. This is difficultbecause the connection point for both is the bushing capacitance tap on the unit under test. The BIDDLE® PD/RIVDetection System multiplexes the picocoulomb and microvolt signals onto a single connection cable from thebushing tap and then splits them apart to drive both a P.D. Detector and an RIV meter.Circle 88
