Dielectric loss tangent testing instrument

Electric loss value in insulation materials is important indicator to evaluate progression of deterioration in the materials as well as to design energy saving machines.

Partial discharge measuring instrument

Partial discharge in electric insulating materials reduce quality or strength of them. Diagnosis of progression degree of the deterioration is possible by measuring quantity of partial discharge.

Impulse testing instrument

Impulse test instrument for testing rotator windings.
Diagnosis of coil turns and layer short circuit is available with simple operation.

AC Magnetic characteristics measuring instrument

Magnetic materials for transformer and motor play the most important part in converting energy, and it should be designed to have a smallest electrical loss

Instrument Transformer testing set

Measuring the electric power justly is vital when trading in the power. SOKEN instrument transformer testing set can measure errors in measuring devices for the electric power preciously.

Insulation tester

Insulation diagnosis is necessary to confirm quality and to secure safety of electrical appliances.

Hot line coil winding resistance meter

Knowing the actual temperature rising value in the coil windings during operation is very helpful for safety evaluation and minimizing energy loss in electrical equipment.

Resistance meter

From a view point of energy saving, resistance value in a large current circuit need to be paid attention. Introducing 4-terminal measuring method, low resistance can be measured preciously.

Automatic Measuring System

SOKEN can offer measuring instruments with a testing power supply and software to meet various requirements.
