Profile:

The KDCT-120P is a high-performance, portable analyzer developed by Wuhan Kaidizhengda Electric Co., Ltd. It utilizes advanced variable frequency technology to perform a wide range of tests on CTs and PTs. The device features a TFT color LCD touch screen for intuitive operation and a built-in thermal printer for on-site result printing. With its large internal memory and USB data export function, it simplifies data management and report generation. The KDCT-120P is designed for efficiency, allowing for one-button operation and automatic calculation of key parameters like knee point voltage and error curves.

Features:

  • Comprehensive CT/PT Testing: Supports a full range of tests for both Current Transformers (CT) and Potential Transformers (PT), including protection, metering, and GIS bushing types.
  • Advanced Variable Frequency Technology: Employs advanced frequency conversion principles for accurate and reliable measurements.
  • Automated Analysis: Automatically detects 5% and 10% error curves and calculates the knee point value and ALF (Accuracy Limit Factor).
  • One-Touch CT Operation: Features a convenient one-button operation for CT testing, with the ability to auto-detect nameplate parameters.
  • High-Current Output: Equipped with a built-in 50A current source, supporting current-method testing for CT ratio and polarity.
  • Secondary Winding Withstand Test: Capable of performing AC withstand voltage tests on secondary windings.
  • Three-Channel Synchronous Test: Supports three-channel synchronous testing for current-method ratio measurement.
  • On-Site Printing & Data Storage: Includes a built-in thermal printer and can store up to 10,000 sets of test data, which is retained even after power-off. Data can be transferred to a PC via USB drive for report generation.
  • User-Friendly Interface: Features a TFT color LCD touch screen for simple and convenient operation.
  • Portable and Durable: Compact and lightweight design (only 10kg) with good shock resistance for a service life of at least 10 years.
