Description

The SGVF series of inorgent amplification capacity test power supplies is a set of AC voltage sources that adjust the output voltage and frequency. The main design is for transformers, resistors, transformers factory and field test power supply, the perfect replacement for the test generator set. It can also be used as a test power supply for series resonance and industrial transformers, replacing traditional linear variable frequency power supplies as well as regulators and fast protection devices.

SGVF series infinity amplification capacity test power supply provides capacity coverage of 500kVA-6000kVA, voltage range coverage of 0.69kV-10kV, frequency coverage of 16.6Hz-200Hz (special requirements 0.1-250Hz), single-phase or three-phase output, local discharge less than 10pC (special requirements can be less than 5pC), THD less than 3%.

Different test products and different test projects for the power load requirements are often different, different power factors, linear or transformed loads, the use of conventional test generators or linear variable frequency power supply needs to pay special attention to the power factor or even can not meet the test requirements. The SGVF series of inorgent amplification capacity test power supplies provide extremely large power factor load ranges of -0.05-1-0.01, 0.01Hz frequency accuracy, making up for the lack of generators. The extremely strong transient responsiveness and full current output characteristics over the full voltage range also compensate for the birth defects of linear power supplies.

The SGVF series of infinity zoom capacity test power supplies are container-designed and can be placed in outdoor venues or indoor equipment without special ground handling. Especially convenient for upgrading old experimental stations. The cooling is designed with air-cooled structure, which is simple and easy to maintain.

SGVF series infinity amplification capacity test power supply has the characteristics of rapid response, compared to circuit breaker protection response time is more than 1000 times shorter, in the event of system failure, effectively avoid fire and explosion and other unnecessary consequences. At the same time, rapid response also allows the test power supply to complete some rapid load transformation tests, such as load tests with load tap switching. The test power supply can quickly switch voltage and current following during the test to achieve a stable output of the test power supply.
