Primary Current Injection Test Set:

Primary Current Injection Test Set is used to inject a known amount of current into the primary winding of a current transformer (CT) or a power transformer. By simulating the actual operating conditions, this test set helps validate the accuracy and performance of the CTs and transformers.

Compact Design:

  • Utilizing raw materials PVC panel, this Primary Current Injection Test Set boasts a compact and lightweight design.
  • Its volume is only 30% to 70% of similar products, making it smaller and lighter than other brands, ensuring easy handling and portability.

High-Resolution Display:

  • Equipped with a 6.5-digit LCD display for voltage and current measurements, this test set provides precise and accurate readings.
  • Additionally, a 128*64 dot matrix LCD display enhances data visualization, making it more intuitive and faster to read.

Wide Measurement Range:

  • The test set offers a wide measurement range, catering to various testing requirements.
  • It can measure voltage up to several kilovolts and current up to several thousand amperes.

Relay Protection Tester:

Secondary Current Injection Test Set is designed to inject current into the secondary winding of a CT or a voltage transformer (VT). It is used to protection relay test set connected to the secondary side of these transformers

D/A Conversion and Low-Pass Filtering:

  • The Relay Protection Tester utilizes advanced D/A conversion and low-pass filtering techniques to generate precise and stable output signals.
  • This ensures accurate testing of protective relays under various operating conditions.

AC and DC Output Ranges:

The tester offers a wide range of AC and DC output capabilities:

  • AC current output is options of 30A per phase or 180A (three-phase parallel), and AC voltage is up to 120V AC per phase.
  • DC current output is up to 10A DC per phase, and DC voltage output is about 160V DC per phase.

Frequency Range:

The tester covers a wide frequency range from 0 to 1000 Hz, allowing for comprehensive testing of protective relays at different power system frequencies.

High Measurement Accuracy:

The Relay Protection Tester boasts an accuracy of measurement of less than 0.1 ms, ensuring precise timing measurements critical for protective relay testing.
