回路电阻测试仪
Uses
This instrument is lightweight, efficient, accurate, and fast, making it ideal for circuit measurements in power generation, power transmission, substations, and industrial and mining enterprises. It employs a “four-wire” current and voltage measurement method, enabling the measurement of minute resistances in high-voltage switches, circuit breakers, and the metal contacts of relays.
Function
1.Complies with the People’s Republic of China’s DL/T 845.4-2004 electrical standard.
2.Standard RS-485 and Bluetooth communication enable remote data upload.
3.The built-in lithium-ion battery pack does not require an external AC power source.
4.The test power supply is a continuous, constant-current source (not a pulsed source).
5.Selectable test current outputs of 200 A, 100 A, and 50 A.
6.Apply a 200A load for a continuous 60-second test.
7.The change in output current from a short-circuit condition to full load shall not exceed 1%.
8.Resistant to power-frequency interference; suitable for use in 1,000 kV substations.
9.Monitor the battery charge level and internal temperature in real time.
10.Features a USB port for exporting test data.
11.Features a high-brightness 4.3-inch color touchscreen LCD display.
