Sivananda Make 230 V 0-50hz Electric Transformer Ratio Meter, For Winding Testing, Color : Light Grey

Listing ID #2925682

Microprocessor based Automatic Ratio Meter is the rst automatic ratio meter in the country giving digital display of ratio directly. The instrument without any need of balancing precisely & accurately measures the voltage transformation ratio of single phase/3-phase delta or star, without neutral, Zig zag connected transformers, CTs & PTs, Power Transformers.

Test Voltage The Instrument provides isolated test AC voltages of 8V,40V,80V, which enable the testing of both power transformers & Cts. Display LCD displays the ratio i.e. ratio of high voltage winding to low voltage winding at low ux in the core. Ratio is displayed in 0.8 – 12000 ** by auto ranging.

Principle of Operation This micro-processor based Instrument uses ratio-metric circuit in which the ratio of test specimen is compared with known internal standard. Protection Instrument is protected against any wrong connection across the transformer. Fast acting VBO trips in case of stepping up of test voltage
