NR5220 series current transformer secondary circuit load tester

The secondary circuit load tester for current transformers uses a single power supply input port and only needs two test ports to complete the load test items of CT/PT (current transformer/voltage transformer). The wiring method is very simple, effectively reducing labor intensity and greatly improving work efficiency. The instrument adopts a large-screen LCD display, simple operation, clear graphic display, intuitive and convenient. Compared with similar products, it is smaller and lighter, making it very suitable for power testing.

Product Introduction

　　The secondary circuit load tester for current transformers uses a single power supply input port and only two test ports to complete the load test of CT/PT (current transformer/voltage transformer). The wiring method is very simple, effectively reducing labor intensity and greatly improving work efficiency. The instrument adopts a large-screen LCD display, simple operation, clear graphic display, intuitive and convenient. Compared with similar products, it is smaller and lighter, making it very suitable for power testing.

Main Features

　　◆ Can realize three-phase three-wire, three-phase four-wire, single-phase automatic measurement;

　　◆ The instrument has an automatic range switching function to ensure testing accuracy;

　　◆ The use of electronic principle circuits combined with DSP technology ensures good test stability and strong anti-interference ability;

　　◆ After the measurement is completed, the instrument automatically calculates various parameters related to the load, facilitating customer analysis and testing;

　　◆ For secondary load testing, a clamp-type ammeter is used to sample the current, eliminating the need to disconnect the secondary circuit. Online measurement without power interruption can be achieved;

　　◆ Can store 480 sets of measurement data, which can be retained for ten years after power failure;

　　◆ Large-screen display with Chinese interface and RS-232 communication interface.

Technical Parameters
