Toroidal Turns Platforms:??

  • TTPT100:?5 T - 1000 T ,????TTPT1000:?500T-10000 T?
  • Accuracy :?+ 0.2% + 0.5T for high and? medium permeability cores at suitable test frequency.??
    Internal? Diameter? must be able to pass a wire as thin as 0.2 mm.? External Diameter as high as 200 mm.
  • Test Frequency Selectable 50, 100 , 500, 1, 5, 10 KHz.?
  • Test Voltage adjustable 100mV to 1V in steps of 50mV.
  • The Platform has 2? connections for the coil and 2 for the probe wire. Measurement? principle is? based on dynamic? comparison of the voltage? across one turn and the coil. You will be able to get the polarity or winding indication? with respect? to the one? turn reference.

Possible Tests:Can?? test Turns, Inductance, Polarity, DC resistance at? one go by controlling the instrument by PC? and connecting the coil to the platform.

Turns test for non-toroidal coils or transformers:?Test turns for? any transformer or coil with core . The core can be EI,EE,UU, RM, POT? etc.? You must be able to pass any thin probe wire around the winding. The core must not have air gap.

3 modes of? testing for Toroidal Coils .?
Mode-1: Turns and polarity with turns? platform. Mode-2: Inductance / DC Resistance direct.
Mode-3:Turns, Polarity, Inductance, Indication of Shorted turns? and? DC Resistance? all? at one go dyanamic test? with RS232C control.? Set? limits? for PASS/FAIL. Take? printed report if required.?Test more than 2,000? CTs per? shift.??

Bobbin? Turns Test? Platform?(BTPT 10000)
Range:??? 1 T to 10,000T? in 2 ranges.??
Accuracy:? + 0.5% + 0.5T.
Coil :?I.D. >11mm , O.D.< 60 mm , Ht < 80 mm
Calibration for Bobbin Turns test Platforms only: With master coil required for each type of coil.
The platform has? two connections with a probe rod. You? have to insert the coil in the vertical open? probe and connect? the wire ends to the terminals. You may need a master coil as the? pickup of the magnetic probe varies with geometry and placement. You have to check? with a standard coil? with? known number of? turns and calibrate the meter.

Possible? tests:You will be able to? test? Turns, Inductance, Polarity, DC resistance? on individual test basis. While connected to? platform you can test? Turns and polarity . You can also test inductance, and DC Resistance while directly connected to the? instrument, without? turns platform.

Vasavi Digital Turns Tester with RS232C Control : (PC Control Software)
The instrument is controlled through external PC through RS232C port. The system software works on Windows platform. All the test results will be transferred to a database files with connected file name. The database table is compatible to fox-pro table. You can import these files to other softwares for creating graphs and other analysis.

User? Friendly Menu driven software
The instrument? not only? tests and displays the results but? also analyses the tested? results against? set? limits on each parameter.Each? test? can be defined with different? test? parameters and different test conditions like Test? frequency. After completing the tests as per defined procedure the results? are dynamically displayed after each test on the monitor of the system.

Password Requirement:?The control software expects two levels of users.?
Level-1 user - Person with Password: A person? who? understands the transformer, its windings, drawings,? specifications. This? person? will?? be? provided with the password? and? will be able to access all menu items.
Level-2 user - Person without Password: This persons can select the test file, test the components and take reports.

Testing Multi-pin transformers at one go?with Pause Option:?You can test multipin component with this option. The system pauses before each test. Suppose that you have defined 10 tests with pause option. While testing, the display prompts you to press a key before each test. Before pressing the key change the input connections for the coming test. You need not to remember or note the test results for each test. The system consolidates all the defined? tests , displays the tested results and also prompts you Go or NO GO based on limits entered for each parameter. Further you can also take? a report on the printer if selected and connected.

Vasavi Digital Turns Tester can test Inductance,

  1. Capacitance
  2. AC Resistance
  3. DC Resistance
  4. Impedance
  5. Transformation Ratio?(for transformers with TR JIG)
  6. Turns and winding polarity?.?
  • Simultaneous indication of? value & tan delta. Very high resolution of tan delta. 0.0001
  • Optional RS232C port for PC control with control software for MULTI-TESTING.

Other Features
Kelvin Test:?For Direct connection without platform the? instrument? has 2? pairs of connections. One pair for drive and the other pair for sense. This separate connection can be utilized for? testing transmission / transformation parameters. You will be able to test transformation ratio.

Impedance Test:?Though impedance is? 2 pin test, it also involves connection of load impedance or load resistance. If you are testing impedance only,? you can connect the load impedance permanently to the test jig.


Winding? Polarity? Test:??In? addition? to? Transformation ratio test,? the instrumentalso checks the polarity? of? winding? with? respect? to reference winding. If? the? secondary is? not in phase with primary then the system displays? -ve sign.

Unbalance Test (with RS232C control):?This test calculates the percentage unbalance of the previous two tests. You can measure unbalance of Inductance, Capacitance, Resistance and Impedance.? If the individual readings are R1 and R2 then
UNBALANCE=?(R1- R2)??x 100
(R1+R2)
