WUHAN HUAZHONG HUANENG HIGH VOLTAGE&TECHNOLOGY DEVELOPMENT CO., LTD.  

Product Name: Transformer No-Load & Load Capacity Tester Model NO.: HNRL-III Power Source: AC220V Weight: 0-100Kg Control: Computer Control Display: Digital Loading Method: Static Load Load Way: Electronic Load Type: Universal Testing Machine Trademark: Huaneng Transport Package: Wooden Box Origin: Wuhan China Product Description HNRL-III Transformer Capacity Load TesterIntroductionHNRL-III can test the transformer capacity, type, no-load current, no-load loss, short circuit (load) loss, resistance voltage, etc. It is small in volume, light in weight, in high accuracy, with steady property, easy to operation can replace the traditional testers. It is displayed by LCD, operated by menu, with friendly interface, is the first choice for all customers. Parameter1 .Built-in power output range Voltage: 0 ~ 10V Current: 0 ~ 10A2.Characteristic test power input range Voltage: 0 ~ 750V Current: 0 ~ 100A3.Test accuracy Voltage and current: + 0.2% Power: + 0.5% (Cos phi >0.1), + 1% (0.02<Cos phi <0.1)4.Working temperature -20ºC~+60ºC5.Charger power requirements: AC160V ~ 265V6.Insulation 1) Capacity testing, voltage and current inputto shell insulation resistance ≥100MΩ 2) Charging power supply input to shell frequency withstand 2KV(RMS), 1 minute.7.Size: 32cm * 25cm * 12cm Weight: 3KgFeatures1.Measure the transformer load current, load loss, short-circuit voltage, short circuit (load) losses, capability.2. equipped with contained power supply, automatic generation of three-phase high-power test power supply3. It can automatically correct waveform distortion, temperature, voltage and current (short circuit test under non-rated current condition). Operators can automatically calculate the corrected results only by inputting correction index instrument according to the type of transformer. It is very suitable for units without short circuit test conditions of slightly large capacity transformers.4. Width limit of voltage circuit: The maximum voltage can be measured to 750V, and the accuracy can be guaranteed without switching gears. The instrument itself will not be damaged by the wrong selection of voltage gear.5. Data (test sample set, the measurement results, the test of time, etc.) with power-down storage and browsing features, you can store 500 set of experimental results with computer on-line data transfer.
