Distribution Transformer Winding Material Inspection Device

The MOEORW-WC800 is a portable, multifunctional, and high-precision comprehensive testing device for distribution transformers. It is designed for power, quality supervision, and other units to quickly determine the winding material of transformers and measure capacity and loss parameters.

The equipment can accurately identify the copper/aluminum windings of a 10kV transformer , supports blind testing of 10kV/35kV/110kV/220kV transformer capacity, and simultaneously measures key parameters such as load loss, no-load loss, short-circuit voltage, no-load current, and turns ratio. It also automatically performs waveform, temperature, voltage, and current corrections.

1.It can accurately determine the material of a 10kV transformer.
2.It can blindly measure the capacity of 10kV distribution transformers as well as the capacity of 35kV, 110kV, and 220kV transformers.
3.It can measure the load loss, no-load loss, short-circuit voltage, and no-load current of various types of transformers.
4.It can automatically perform waveform distortion correction, temperature correction, voltage correction (no-load test under non-rated voltage), and current correction (short-circuit test under non-rated current). Operators only need to input the correction index according to the transformer type, and the instrument can automatically calculate the corrected result. It is very suitable for units that do not have the conditions to conduct short-circuit tests on transformers with larger capacity.
5.It allows external voltage and current transformers to be connected for extended range measurements, and can measure test samples with arbitrary parameters.
6.The tester uses a 7.0-inch, 800*480 pixel dot matrix, high-brightness, wide-temperature, wide-viewing-angle, fully touch-screen industrial-grade color LCD that is clearly visible in sunlight.
7.All- English menu and graphical operation prompts enable a user-friendly human-computer interaction, while the touch buttons make operation simpler and adaptable to all seasons.
8.Users can print out the test results at any time using a mini printer.

Power Operation and Maintenance On-site Inspection
rapid on-site testing of transformer winding material, capacity, and operating parameters in substations and power distribution rooms .
 

Quality supervision and spot check enforcement
Market supervision and power quality inspection departments conduct random inspections and verifications to distinguish between copper and aluminum windings and prevent the substitution of aluminum for copper.
 

Production and factory inspection
Transformer manufacturers conduct factory quality inspections to verify whether indicators such as loss, turns ratio, and capacity meet the standards.
 

Bidding and Acceptance Verification
Qualification verification is conducted during power grid bidding and project acceptance to ensure that equipment parameters are consistent with the tender documents.
 

Laboratory precision testing
Standard tests and data calibrations are conducted in a laboratory environment, including no-load, load, and short-circuit impedance tests .
