Huazheng Primary Current Injection Test Set

I. Product Summary

Applications
The HZDL 130 Primary Current Injection Tester (hereafter referred to as "the Current Booster") is a self-developed device integrating advanced CNC technology and high-performance components. Featuring low power consumption, a high-capacity self-regulating voltage stabilizer, and a high-permeability magnetic core converter, it offers superior output power, compact design, and lightweight portability.
Designed for busbar protection verification and current transformer testing, it is widely utilized in power systems, railways, petrochemical plants, and metallurgical industries for R&D, production, and on-site electrical testing.

Key Features

High-Precision Measurement:

0.5-class accuracy with 6.5-digit LCD for voltage/current display.

0.2% current stability and true RMS continuous adjustment.

Intuitive Operation:

128×64 dot-matrix LCD for real-time data visualization.

Display lock function for accurate CT ratio reading during experiments.

Advanced Functions:

Auto CT polarity detection and ratio verification (no manual intervention).

Integrated timer (0.01–9999.999 s) and self-locking mechanism.

Enhanced Durability:

Anti-wear PVC panel with robust construction.

Compact size (30–70% smaller than competitors) and portability.

Safety & Efficiency:

Overcurrent/overvoltage protection.

Short-time operation mode (5-minute duty cycle) and batch testing support (≤2.5 minutes with 10-minute cooldown).

Operational Guidelines

Pre-Test Checks:

Verify wiring integrity and terminal contact quality.

Ensure output terminals form a closed circuit to enable current flow.

During Testing:

Immediately power off if abnormalities occur (e.g., display failure).

Use supplied 10 A/mm² copper conductors (standard: two 3-meter cables).

Duty Cycle Management:

Continuous operation ≤5 minutes; ≤2.5 minutes for batch tests.

Allow 10-minute cooldown between cycles. For extended use (30+ minutes), ensure thermal management.
