PRODUCT OVERVIEW

FTT701 Power Transmitter FTT701 is a signal conversion device that converts conventional voltage signal (eg: 100V) and current (eg: 1A) into 3.25V/1V small signal voltage and current of deep fusion terminal, customized zero sequence Voltage and zero-sequence current have higher accuracy and stability than the direct output of large signal sources below 100mV. The conversion device adopts an active zero-flux hardware conversion circuit design with high response rate. Using this conversion device can simply and quickly expand the original power distribution terminal test equipment (relay protection tester, standard source, etc.) The original test equipment has the ability to detect small signal terminals after being expanded, and the repeated utilization rate of instruments and equipment is improved by a low-cost method.

PRODUCT FEATURES

Active signal conversion zero-flux technology ensures low distortion and high stability of signal conversion.

The large signal signal input adopts the power line to connect to the banana socket of the source, the output adopts the shielded cable, and a group of signals is directly connected to the small signal multi-function meter, which avoids signal interference, saves the user wiring time, and is convenient and fast.

APPLICATIONS

Use traditional power source to debug, calibrate and test the primary and secondary fusion terminals.

Use the manufacturer's own traditional power source or relay instrument to apply conventional large-signal power, and convert it into a small signal required for primary and secondary fusion through the FTT701 power transmitter. The small signal is output in two groups in parallel, and one group provides the primary and secondary fusion terminal is sampled, and a group is provided to the small-signal multi-function meter for calculation, so that the data obtained from the sampling and calculation of the small-signal multi-function meter can be used as a standard reference to debug, calibrate and test the power distribution terminal.

Device Exception Handling

When the equipment is in use, if there is an unknown situation, the user could check the following table to find the reason and deal with it.

Phenomenon	Cause Investigation	Handling Method
The output value has large value	1.Check whether the source can be outputed and whether the dosage is correct 2.Check if the power transmitter is powered	1.Correct operation of source dosing 2.Power up the power transmitter
The output value has small value	1.Please confirm whether there is an error in the accuracy of the source output value, and whether the user source output accuracy below 10V meets the requirements 2.The accuracy of the meter used for measurement is not enough (EG: FLUKE 17B+), causing errors and cannot be used as a reference	Choose a source with high precision Choose the meter with high precision(EG:FTT150-B42)

Notes

The negative terminal of the voltage input and the negative terminal of the small-signal voltage output share the same ground. Please do not connect the voltage input to the 220VAC mains. If the LN is reversely connected, it will cause an electric shock hazard when connecting the online signal. The normal source output is an isolated output and will have no effect.
To sum up: Do not operate the wiring with power on.

Small signal output should not be connected to phase sequence or phase-to-phase short circuit to avoid damage.
