Digital three-phase ammeter

1、 Function of digital three-phase ammeter:

A digital three-phase ammeter can be used in conjunction with transformers to measure three-phase current parameters in the power grid. It uses digital LED display and has the advantages of high accuracy, strong isolation, stable performance, and anti vibration. It can set PT and CT changes and can directly replace the original pointer three-phase ammeter.

1. Digital three-phase ammeter:Equipped with high-performance processing chips and independent measurement chips, it has high measurement accuracy and fast operating speed.
2. Digital three-phase ammeter: measures three-phase current, CT can be set arbitrarily.
3. Digital three-phase ammeter:Adopting LED digital display.
4. Digital three-phase ammeter: Input rated current: AC5A AC1A.
