CY-RAM2000 Parallel-cables current balance detector

‘CY-RAM2000 parallel-cables current balance detector’ is designed for easy installation in a small space without removing the main bus or cable. It consists of two parts: flexible rogowski coil probe and electronic modules with a display.The instrument can simultaneously display two wires AC current, and also shows the current difference & current unbalanced degree between two wires. Mainly used for various power bus current measurement, and two current balance detection.

Features:

Flexible,lightweight, beautiful appearance

Simple and quick installation in small space

without high voltage in secondary open circuit

No iron core saturation and damage when overload

Excellent linearity

Multi-size optional

Application:

General measurement and protection for strong mobility or space-constrained or uninterrupted power systems

Power instrumentation, electronic multi-function energy meter and field calibrator, instrumentation measurement and protection

E.g.

parallel-cables bus current balance detection

Three-phase load current balance detection of power system;

Current detection of large load power system lines.

Attention:

1. To achieve best accuracy, flexible rogowski coil measurement probe should keep consistent with A, B channel when connection.

2. When the display shows low power, display dim, can not boot, you should replace the battery.

3 When the display is not normal (e.g. only two lines are displayed), remove the battery and reload it.
