Transformer Parameter Meter - Coefficient

The microprocessor-based device "Coefficient" is designed to monitor the parameters of high-power transformers and is used to equip the operational services of power systems and enterprises manufacturing power equipment, and can be used both in shop conditions and at the open switchgear of substations.
The device allows to measure the following parameters for transformers of all schemes and connection groups according to GOST 3484 for transformers of all schemes and connection groups according to GOST 30830:
- transformation ratio;
- no-load losses at low voltage;
- short-circuit resistance.
The device can be used as an alternating current voltmeter and ammeter. Simultaneous use as two galvanically isolated voltmeters or voltmeter and ammeter is possible.
