Product Overview：

As the core equipment in power systems, transformers play a vital role in ensuring long-term stable and reliable operation, which directly impacts the overall system stability and reliability. According to the State Grid's preventive testing regulations, new transformers must undergo regular turns ratio or voltage ratio tests before commissioning. Traditional transformer ratio testers suffer from cumbersome operations, unintuitive readings, and the need for manual conversions, typically yielding only single-phase ratio data. This innovative transformer ratio tester overcomes these limitations with a large high-resolution LCD screen for field use, featuring Chinese menu prompts for intuitive operation. It performs three-phase ratio tests in a single operation, delivering rapid testing and high accuracy.

Product Features: ​ 

2.1 The three-phase CNC sinusoidal inverter power supply features soft start and soft stop functions, ensuring rapid testing speed and high precision.

2.2 Testing functions for three-phase transformers, single-phase transformers, PTs, CTs, and Z-type transformers, including ratio, group, and polarity.

2.3 The three-phase test features line-to-line voltage ratio, line-to-phase voltage ratio, turns ratio, vector diagram, and group connection testing functions.

2.4 CT ratio polarity test function.

2.5 It has angular difference testing function in single-phase test.

2.6 The tap position can be tested up to 99 positions.

2.7 The measurement range is wide, with a maximum of 2000.

2.8 High/Low Voltage Reversal Alert.

2.9 Output short-circuit alert.

2.10 The clock and date display remain operational without power loss; data is stored locally with 100 test records, and the stored data can be transferred to a PC.

2.11 Thermal printer printing function.

2.12 Compact and lightweight, making it easy to carry and use.​
