Ler maisCurrent Ratio Tester Three Phase Transformer Turns Ratio TTR Tester The ratio test ensures that the transformer windings have the proper turns to produce the voltages required. The ratio is a measure of the voltage applied to the primary terminals to the voltage measured at the secondary terminals. What is the purpose of transformer turns ratio test? […]

Como é que se testa a resistência do enrolamento de um transformador
Ler maisⅠ: How do you test the winding resistance of a transformer? Transformer winding resistance measurements are obtained by passing a known DC current through the winding under test and measuring the voltage drop across each terminal (Ohm’s Law). Winding resistance in transformers will change due to shorted turns, loose connections, or deteriorating contacts in tap changers. Regardless of […]

Ler maisWhy You Need Contact Resistance Test? The contacts in the circuit breaker needs to checked periodically to ensure that the breaker is healthy and functional. Poorly maintained or damaged contacts can cause arcing, loosing phase, and even fire. This test is especially important for contacts that carry large amounts of current (e.g. switchgear busbars) because higher contact resistance can lead to […]
