Albany, NY -- (SBWire) -- 11/28/2018 --Advanced winding analyzers and surge testers are being widely used as standard calibrating instruments.In the past decade the electronic and electrical industry saw the advent of many technically advanced instruments being used in various fields. The ease of usage and efficiency provided by this equipment haveaugmented the increase in demand for electronic and electrical equipment. However, the demand of this equipment depends upon the reliability and efficiency provided by device.High voltage testing has gained significance in the past decades due to this factors. Advanced Winding Analyzer and surge testers are used for trend analysis which will prevent downtime due to less equipment failure and give increased equipmentreliability.

Surge testers use the principle of impedance balance to test the quality of electrical windings. They act as a capacitive-discharge system. A capacitor is charged with high voltage and then discharged into the winding, through a solid state assembly. This sequence is repeated thus stressing the insulation of the winding with high voltage pulses. The resulting voltage decay pattern of two winding is then displayed on the CRT. The waveform pattern will be perfectly superimposed for good windings but in case of a defective winding a double wave pattern will appear on the screen as one wave pattern from the good winding plus the erratic pattern from the faulty winding. Surge testers not only tests ground insulation, but more importantly, it tests turn-to-turn coil-to-coil and phase-to-phase insulation.

If as few as one turn is shorted the surge test till detect this fault.Advanced winding analyzersdetect and evaluate winding faults by simulating conditions that equipment experience during startup and normal operation. It performs all requested tests, stores the results, and continuously monitors voltage levels while testing. If the analyzer detects a weakness in the insulation, the test is interrupted, the operator is alerted, and all test parameters at the time of the interruption are reported. This analysis includes surge testing, polarization index testing, DC high potential testing, winding resistance testing, and insulation resistance testing.

However, traditional analyzers and surge testers have several shortcomings. The test results provided areless reliable. The operators working with the instruments my lack awareness about the testers. Automation is being used as an effective tool to overcome this problems. A computer and IP network attached to the testers are used to display the accurate result. The computers are also used to keep a record of the anomalies in voltage. Thus it becomes to take preventive measures. Advanced analyzers and surge testers are used for quality checks and spare testing throughout the manufacturing process of coils, motors and generators. Large screens, high operating frequencies and high portability is inclining the market towards advanced winding analyzer and reliable surge testing.
