The 7500A Three Phase Long-term Running Primary Current Injection Test Set is designed for conducting temperature rise tests. This type of test is crucial for determining the thermal performance and reliability of electrical equipment over an extended period of operation. The primary current injection test set is used to simulate the actual operating conditions and to ensure that the equipment can withstand continuous operation without overheating.

1. Input voltage: AC220V/380V ± 10%50Hz ± 1.
2. Output current: 0-20000A (according to customer's demand).
3. Output voltage: 6V-24V(according to customer's demand).
4. Duty cycle: 8hours(according to customer's demand)
5. Ambient temperature: -10℃to 50℃).
6. Current accuracy: ≤1.0% (F.S).
7. 16-way temperature detection (according to customer, s demand).

1. The control screen accepts the IPC.
2. Controller parameters can set to do the same batch when the power is off without needing resetting, permanent save!
3. Test result can save 50 records for recording and printing.
4. 9 inch LCD touch screen display, PLC control, high speed thermal printer.
5. Real-time display output current, time results, with intuitive display.
6. Perfect over current protection, arbitrary setting is available for target output current value,  current upper limit and current endurance time
7. The output current can be regulated and operated as three phase/single phase. and it also can automatically gain to make sure the three-phase output which can be in balance.

Primary Current Injection Test Set is a necessary equipment in various industries that require high current in electrical commissioning. It is used in power plants, transformer and distribution stations, electrical manufacturing plants and scientific research and laboratory units. It belongs to the short-term or intermittent working system. The HMSLQ Primary Current Injection Test Set produced by our company has the characteristics of stable performance and convenient use and easy maintenance.
