As renewable energy systems scale, connecting distributed generation assets to the main utility grid demands strict compliance with grid codes and protection standards. ISTS provides turnkey electrical installation, testing, and commissioning services tailored for Solar PV farms, mini-hydro plants, and Battery Energy Storage Systems (BESS).
From step-up transformer substations and MV switchgear panels to anti-islanding relay verification and power quality assessment, our engineers ensure your clean energy facility safely converts, steps up, and exports power to the national grid without operational bottlenecks.
Full assembly, cabling, and termination for step-up transformers, solar inverter stations, and central MV distribution boards.
Comprehensive calibration of voltage, frequency, and anti-islanding protection relays to ensure immediate grid disconnection during fault conditions.
Insulation power factor, VLF Hipot, and sheath testing for long-distance underground medium-voltage collector networks.
Interconnection testing, harmonic distortion analysis, and protection scheme validation for Battery Energy Storage Systems.
Connecting renewable assets requires explicit approval from Suruhanjaya Tenaga (ST) and Tenaga Nasional Berhad (TNB). ISTS manages all field testing procedures strictly according to the Malaysian Grid Code and relevant IEC 61727 / IEC 62116 standards.
We deliver certified testing documentation, single-line diagram (SLD) redlines, and formal witnessing sign-offs necessary to secure your Interconnection Facility Agreement (IFA) and achieve Commercial Operation Date (COD).
Anti-islanding protection ensures that solar or hydro generators instantly disconnect from the main utility grid during a grid outage, preventing dangerous back-feeding that could harm utility maintenance personnel working on the lines.
We perform Very Low Frequency (VLF) Hipot testing, Insulation Resistance (IR), and outer sheath testing to detect installation damage or insulation breakdown along extended cable trenches before applying grid power.
Yes, our certified competent engineers handle formal testing execution and documentation witnessing required by ST and TNB representatives prior to plant synchronization.
