Brand New Power Transformer No-Load Load Capacity Tester
Darui Electric recommends for you
Product Features
1. This instrument features exquisite circuit design, unique approach, superior performance, and powerful functionality, fully meeting the requirements for on-site capacity testing of distribution power transformers.
2. The instrument internally adopts advanced A/D synchronous AC sampling and digital signal processing technology, making it simple to operate, convenient to wire, and providing accurate and reliable data, solving the challenges of distribution transformer capacity testing. It can also display and print measurement data of interest to users.
3. This instrument is mainly used for capacity testing of distribution transformers. Its built-in test power source can complete capacity tests for up to 100 units of 2500KVA and below distribution transformers on a single charge.
4. The human-machine interface of this instrument uses a blue screen (240 * 128) full Chinese character graphic display, with strictly hierarchical menus that guide you step by step through the test. Simply power on, press any key, and the menu provided by the instrument will guide you through the required test. Using this instrument can greatly improve work efficiency and reduce labor intensity.
