product overview

The ETHG-B transformer tester is designed for:
1. Perform fully automatic testing on the characteristics of various protection, metering, TP, GIS bushing, and other (CT and PT) transformers,
2. Suitable for both laboratory and on-site testing.

Product characteristics

Support detection of CT and PT (protection, metering, TP) steady-state and transient parameters
Adopting advanced variable frequency power supply technology, the excitation inflection point voltage (volt ampere characteristic) can reach up to 30KV
Without the need for external auxiliary equipment, all testing items can be completed on a single machine
Adopting an intelligent controller, the operation is simple
Large screen LCD, graphical display interface
Automatically provide the (excitation) inflection point value according to the regulations
High energy precision, supporting detection of 0.2S level transformers
Automatically provide 5% and 10% error curves
Can save 3000 sets of test data without loss after power failure
Support USB flash drive data transfer, which can be read through a standard PC and generate detection reports
Compact and lightweight, very conducive to on-site testing
