GTS(M) work with clients to develop transformer trend of change throughout years by performing transformer assessment test. Other than that, GTS(M) has full onsite testing capability to complete comprehensive transformer testing as part of reliability maintenance program.

The assessment test that we normally performs are as follow;

COMMISSIONING
• Sweep Frequency Response Analysis (SFRA)
• Dielectric Response Analysis (DIRANA)
• HV Excitation Test
• Short Circuit Impedance Test
• Turn Ratio Test
• Vector Group Test
• Insulation Resistance and Polarization Index Test
• Transformer Guard Test

MAINTENANCE
