Transformer Induction Voltage Analyser

Introduction
The Transformer Induction Voltage Analyser is mainly used in the transformer industry.
In addition to the main insulation of the transformer, that is, the insulation between the windings and between the winding and the iron core, the transformer has another important insulation performance index – vertical insulation. Vertical insulation means the insulation of transformer windings at different points and parts with different potentials, including turn-to-turn, between the layers and between the segments. The “Induction voltage test” is the standard of one of the test methods to test the vertical insulation of the transformer.

Ainuo AN968 Series Transformer Induction Voltage Analyser is a professional equipment to test the vertical insulation performance of the transformer .

In micro-electronic transformers, due to the high number of turns and thin wires (for 0.1 mm or less), for several or dozens of turns, compared with normal transformers, the test The current under doubling frequency is less than 50% for 10 turns short circuit.

Experiments show that in case there is an inter turn short circuit, the power factor of the transformer changes, the power of the transformer.

Current, power and power can be used to identify the inter-turn short circuit of the transformer. Power measurement is the best basis for determination. AN968 analyser adopts fast identification to simulate non-destructive testing, no damage to the tested transformer, to ensure accurate testing, high efficiency, ideal for labs and transformer line.
