The transformer(s) is one of the most important equipments in electrical system that affects the reliability of the power system. When there is outage of electricity, it causes loss of chance, property, and even life, as we realize such importance so we are committed to be a part of the security system of customers by providing service teams who are qualified to ensure customers for our following servicing.

Transformer installation, removal and relocation

Transformer pre-commissioning

• Measurement of insulation resistance(IR)
• Measurement of tan delta and capacitance of transformer
• Measurement of magnetizing current
• Measurement of short circuit impedance
• Measuement of voltage ratio
• Check of vector group
• Measurement of winding resistance
• BCT test
