Applicable to temperature rise tests and current load tests for busway, circuit breakers, current transformers, transformers, switchgear, cable joints, guide rails, and other electrical equipment.
1. Features:
1). Built-in high-configuration industrial computer, imported 15-inch true color large LCD touch screen operation, no need for any external auxiliary equipment for testing, fully automatic control, foolproof operation, fast, simple, and convenient:
2). Equipped with automatic current stabilization system, with USB, R485, R232 multiple interfaces, easily connect external U disk, printer, and other devices. Can remotely transmit to remote control terminal for operation.
3). Uses the latest power electronics technology, imported high-precision sensors, strong anti-interference capability, high output accuracy, up to 0.2 class.
4). Just set the target current, no need for manual monitoring, only need to set the test voltage, current, and step size, eliminating tedious tasks such as manual voltage adjustment, manual recording, and curve drawing, reducing labor intensity and improving work efficiency. After the work is completed, data can be read to the computer for review.
5). Equipped with minimum and maximum values for current and temperature, with automatic alarm function when exceeding the limit. Has reliable self-protection functions such as overcurrent, overvoltage, overheat, and short circuit.
6). Equipped with precision adjustment menu, users can adjust error values themselves.
7). User-friendly interface, friendly software interface, complete functions, easily complete calibration work, with current and temperature waveform recording and analysis functions, and can store current and temperature waveforms for more intuitive analysis of the relationship between current and temperature. Make all data and test analysis results clear at a glance.
8). Can display three-phase full current curves, up to 120 temperature curves (according to customer selection). Can be equipped with a micro printer, can print curve charts and test data on site at any time.
9). Can customize test modules according to user requirements, software free lifetime upgrades.
