FY96 Current Transformer Load Box

Lightweight, attractive design, wide current range.

HJ-S10G3 Self-Rising Precision Voltage Transformer

10kV, 0.05 class voltage transformer is a high voltage grade, high accuracy transformer that can verify voltage transformers below 0.2 class, capable of handling a secondary load of 0.25VA at 100V secondary voltage.

EDKZX05-HII Dual-Tone Control Box

This series of control panels is designed for voltage regulation control of 0.5-5kVA test transformers. Working Principle: Adjusts the output voltage of the autotransformer to achieve regulation within the rated voltage range of the test transformer. Equipped with a high-voltage output voltage meter and a low-voltage output current meter, it allows for easy reading of test voltage values. The circuitry for overcurrent protection ensures reliable equipment protection, and the timing alarm circuit designed for convenience during testing. User feedback confirms its simple principle, compact structure, reliable operation, and ease of use, making it an ideal equipment for high-voltage testing.

2. Scope of Work:

Current: (1% - 149%) In (In = 5A)

(5%-149%)In    (In =1A)

② Voltage: (5% - 149%) Un (Un = 100V, 150V, 100V/)

          (5%-149%)Un    (Un =100V/3)

3. Workload:

⑴. Current: TO to TX < 0.12Ω, cosΦ = 1

4. Polarization Error Indicator

Over 5% of rated working current (voltage), when the error exceeds 180%, polarity indication should be addressed.

Note: If the polarity indication is still not present beyond 10% above the rated working current (voltage), it indicates a fault. Do not increase the current (voltage) any further to prevent damaging the instrument.

5. Ratio Error Indication:

The transformer should indicate a ratio error when the rated working current (voltage) exceeds 5% and the error is more than 30% but less than 180%.
