Quality of coil( Q )
Property compared with master (Std.) product.
Inductance of coil(L)

The quality of the tested product is evaluated by analyzing the peculiar free oscillation waveform originated after impressing of impulse voltage.

Products necessary for surge test.
Motor, Transformer, Relay, Magnet, Solenoid, Neon transformer, D.Y coil, SMPS transformer, Choke coil, Noise filter, Degaussing coil, Igniter, All stabilizer, Reactors, Car electric parts, etc.

All winding product during its use generates much higher impulse than real impressed operating voltage, as transient effect, and this impulse up to 10~40 times higher, which may cause to be broken by itself.
Recommendable surge test voltage
  1. Es=[(Eo x 2) + 1000] x 1.4
  2. Es= Eo x 60

Es : surge test voltage
Eo : using voltage of product.

  1. ICWA's formula
    ( ICWA : International Coil Winding Association )
  2. KAST's formula
    Applicable for low voltage products les than 30Volts

Benefits

Convenient use and reliable test result.
Sample memory (Max 60 ea )
Auto decision/ numeric presetting of reference range.
Interface type( RS 232C serial port ) with other computer and auto production line.
Adopting of "amplitude vs phase"
Supplied with calibration report (ISO 17025)
Strong design with high safety components.( Mainly 10 times more than reasonable capacity )

above benefits can be different according to tester models.
