ProSight Transformer Turns Ratio Tester
ProSight Transformer Turns Ratio Tester for PT and CT Polarity Test is a portable transformer turns ratio tester designed for transformer commissioning, maintenance, and quality inspection. It is widely used for testing power transformers, distribution transformers, potential transformers (PT), and current transformers (CT). Featuring a wide ratio measurement range, high accuracy, built-in rechargeable battery, color LCD display, USB data storage, and integrated thermal printer, it delivers fast and reliable transformer diagnostics.
ProSight Transformer Turns Ratio Tester for PT and CT Polarity Test is a professional electrical testing instrument developed to accurately measure transformer turns ratio, vector group, phase relationship, and polarity. It is suitable for testing single-phase and three-phase transformers during manufacturing, installation, preventive maintenance, and field service.
The instrument injects a low-voltage test signal into the transformer winding and automatically calculates the turns ratio by comparing the input and output voltages. It also identifies transformer vector groups and verifies winding polarity, allowing technicians to quickly confirm transformer integrity and wiring correctness. With its automatic measurement process, high-resolution color display, and built-in printer, the LNBB-2000 significantly reduces testing time while improving accuracy. It supports conventional transformers, Z-type transformers, PTs, and CT polarity testing, making it a versatile solution for utility companies, electrical contractors, transformer manufacturers, and industrial maintenance teams.
