MEBZ-3320A Three Channel Transformer DC Resistance Tester
Transformer DC resistanceofMeasurement refers to the testing of semi-finished and finished products in transformer manufacturing, including factory testing, installation, handover testing, and power department testingPreventive testingMust test items that can effectively discovertransformer coilManufacturing defects such as material selection, welding, loose connection parts, missing strands, and broken wires, as well as hidden dangers that exist after operation.MEBZ-3320A Three Channel Transformer DC Resistance TesterIt is a fast testing equipment for measuring the DC resistance of transformers, mutual inductors, generators, and motor windings. It is particularly suitable for simultaneous measurement of three-phase large capacity star connected transformers and magnetic measurement of three-phase five column and low-voltage corner connected transformers, greatly saving time and improving maintenance efficiency.
1Main Features
l All DC resistance data of high and low voltage windings can be measured with just one wiring.
l The neutral point transformer can measure three phases simultaneously, greatly saving measurement time.
l The low-voltage winding of a three-phase five column corner connected transformer can be measured using the magnetic assist method, which has a fast testing speed.
l The instrument has demagnetization function, which can eliminate residual magnetism at once.
l The instrument has a wide range of resistance measurement, high resolution, and multiple current gear options.
l The instrument has a reverse electromotive force protection function.
l The longitudinal test of the DC resistance of the on load tap changer transformer can be completed in one go.
l The instrument has high measurement accuracy, anti-interference, shock resistance, and convenient portability.
l Adopting a 5.0-inch 65K color touch screen, it is easy to operate.
l Built in large capacity non-volatile memory, capable of storing 500 sets of data.
l Built in high-speed micro thermal printer, capable of printing measurement data.
l Built in high-precision clock, real-time display of time.
l It has USB storage function.
