When purchasing a switch characteristic tester, it is usually necessary to compare sensor compatibility, reclosing test capability, low-voltage test configuration, and ease of operation. Compared with solutions that only support a single rotary sensor, this instrument provides multiple displacement sensor interfaces for linear, rotary, universal, and laser sensors, and can adapt to mechanical characteristic measurement for SF6 switches, GIS combined electrical apparatus, vacuum switches, and low-oil/oil-minimum switches.
This tester supports time parameter measurement for reclosing processes such as close-open, open-close, and open-close-open. With a built-in adjustable DC power supply, it can automatically complete low-voltage operation tests for circuit breakers and record the current waveforms and maximum current values of opening/closing coils. Compared with some similar devices that require an external power supply or manual voltage regulation, the operating process is simplified, making it suitable for on-site batch verification tasks.
The sensor installation method is designed for on-site operations, with fewer connection steps, which can reduce measurement errors caused by installation deviation. Data records cover basic items such as opening/closing time, synchronism, and travel curves, making it convenient for procurement personnel to check whether the equipment functions meet operation and maintenance requirements against the technical agreement.
