Transformer On Load Tap Changer Analyzer

1. Equipment Description:

OLTC series on-load tap changer tester is used to test the switching status of on-load switches. Field workers can test the performance of various power transformers' on-load switches without dismantling transformers or lifting switches, display and print the waveform and parameters of the transition process.

 

2. Main Functions:

♦ The instrument has a large output current and is lightweight.

♦ Test YN, Y, and △ type transformers, and display the resistance values directly without conversion.

♦ Can be measured with or without windings.

♦ The waveform display automatically adjusts the resistance and time value amplitude based on the sampling value.

♦ Equipped with complete protection circuits and strong reliability.

♦ Equipped with 7-inch high-definition touch screen and lithium battery (battery for option).

♦ 500 sets of data can be automatically saved internally.

♦ The instrument has both printout and USB interface, equipped with RS232 interface, making it convenient for paperless office work.

♦ Download the app from your mobile phone, operate the instrument through software, upload test data, and facilitate query.
