Product catalog summary

PDC20k High DC Primary Current Injection Test Set Overview
The PDC20k is a high-frequency inversion and linear amplification-based test set designed for high DC current output. It is modular, lightweight, and mobile, making it suitable for various testing environments such as high-voltage DC converter stations and railway stations.

Key Functions

Testing DC circuit breaker (CB) operating current and time.
Measuring internal and contact resistance of DC CBs.

Features

Portable design with a cart for easy transportation.
Utilizes supercapacitor storage for quick power charging.
High accuracy and quick response with minimal ripple.
User-friendly local operation system with automatic test finalization.
Automatic generation of test reports.

Composition and Panels

Includes a system control unit, four DC current output units, and a portable cart.
Control unit features a 7-inch touch screen and various ports for connectivity and measurement.
Each DC current output unit provides up to 5000A output.

Software Features

Main interface includes Ramp test, DC loop impedance test, and system information.
Ramp test allows for incremental current output to test CB action parameters.
DC loop resistance test measures contact and loop resistance.
