PT Prastiwahyu Tunas Engineering Switchgear Testing Bay and Factory Integration Facility

Engineering Rigor Verified by International Standards.

All STAR-E switchboards and power distribution systems are engineered under rigorous testing protocols, complying with IEC 61439-1 & 2 standards for total fault protection and 100kA short-circuit withstand.

how it works

Four stages between the grid and the rack.

stage-01

1. Tegangan Menengah 24kV

Schematic drafting, busbar electrodynamic sizing, and thermal dissipation modeling conforming to IEC 61439-1.

stage-02

2. Proteksi & Transformasi

Direct procurement of certified components from global partners (Schneider Electric, ABB, Siemens, CHINT) and 99.9% pure electrolytic copper.

stage-03

3. LVMDP & STAR-E Switchboard

High-precision sheet metal fabrication, CNC busbar punching/bending, and modular assembly in our Cikarang plant.

stage-04

4. Distribusi Akhir (VOLT-E & LINK-E)

Full primary injection testing up to 6300A, secondary protection relay testing, insulation resistance, and FAT/SAT certification.

the stack

Hardware, control, and the redundancy between them.

Medium-voltage modules, built on Tier-1 components.

Bankable hardware with a 20-year design life, manufactured in Indonesia at our Jababeka II Cikarang facility under Integrated Management Systems (ISO 9001, ISO 14001, ISO 45001). Our in-house assembly bay scales production to 540 free-standing and 741 wall-mounting panels annually, ensuring reliable project delivery.

Fault tolerance designed in, not bolted on.

N+1 topology with static bypass means a single module failure is absorbed without a transfer the load can feel. Every transfer is logged and auditable. The dispatch desk cleared its last IEC 61439-1 & 2 audit with zero findings.

The measurement

All PTE switchgear and power distribution boards are built under stringent quality controls, strictly complying with international IEC 61439-1 & 2 standards for total system protection.

Factory Acceptance Testing (FAT) is where engineering reliability is proven. Every STAR-E, VOLT-E, and partner switchboard undergoes comprehensive primary current injection testing, dielectric insulation checks, and mechanical/electrical interlock validation before site dispatch.
