FREQUENTLY ASKED QUESTIONS
Clear answers from certified lead engineers regarding 20 kV medium voltage equipment, transformer substations, PLN grid connection requirements, and statutory ESDM licensing.
1. 20 kV Medium Voltage & Switchgear Cubicles
How long does 20 kV switchgear cubicle fabrication take from PO to delivery?
Fabrication lead time typically ranges from 4 to 8 weeks depending on component specifications and modular cell configurations (Incoming, Outgoing, Metering). If utilizing standard stock components (Schneider SM6 or ABB UniSec), expedited assembly can be achieved within 3 to 4 weeks, followed by complete Factory Acceptance Testing (FAT) at our Pekanbaru workshop before site dispatch.
What international and Indonesian technical standards do your cubicles comply with?
All switchgear cubicles engineered by Baskara Riau Teknik strictly adhere to IEC 62271-200 (High-voltage switchgear and controlgear), SPLN D3.015-1 (Standard PLN for Medium Voltage Metal-Enclosed Switchgear), and PUIL 2011 regulations. Panels are rated for 24 kV operational voltage, 50 Hz, and withstand 50 kV power frequency dielectric testing.
What circuit breaker brands are used in your 20 kV panels?
We integrate original, certified components based on client Single Line Diagram (SLD) requirements, primarily Schneider Electric (Evolis VCB, Fluokit/SM6 LBS), ABB (VD4 VCB, NALF LBS), and Siemens. All components come with original manufacturer test certificates.
2. Distribution Transformers, LVMDP & Capacitor Banks
What range of distribution transformers can Baskara Riau Teknik supply and install?
We supply, erect, and commission step-down oil-immersed transformers from 630 kVA, 1,000 kVA, 1,250 kVA, 1,600 kVA up to 2,500 kVA with standard vector groups (Dyn5) converting 20 kV grid voltage to 400V/230V industrial distribution. Notable brands include Trafindo, Bambang Djaja (B&D), and Schneider.
What is the role of an Automatic Capacitor Bank in industrial plants?
Inductive loads in factories (such as electric motors, shredders, and heavy pumps) lower the power factor (cos φ). When cos φ drops below 0.85, PT PLN (Persero) imposes heavy monthly kVARh penalty surcharges. An Automatic Capacitor Bank continuously monitors power factor and steps capacitor steps in/out automatically, keeping cos φ between 0.95 and 0.99 and eliminating PLN penalty invoices completely.
3. PLN Interconnection, NIDI & SLO Permitting
What is the difference between NIDI and SLO under Indonesian law?
NIDI (Nomor Identitas Instalasi Tenaga Listrik) is the official digital registry number recorded in the Ministry of Energy and Mineral Resources (ESDM) database, affirming that the electrical installation was built by a licensed contractor holding certified engineers. SLO (Sertifikat Laik Operasi) is the statutory certificate issued after an on-site physical and electrical test conducted by an accredited Technical Inspection Agency (LIT). Both documents are legally mandatory before PLN can energize medium-voltage industrial facilities.
How long does the entire PLN 20 kV connection process take?
Turnaround depends on whether a grid extension (SKUTM/SKTM) is required by PLN. If grid capacity is readily available near the mill gate, substation erection, testing, and SLO certification typically conclude within 30 to 60 calendar days. We coordinate all liaison paperwork directly with PLN UID/UP3 and the dispatch center.
4. Regional Coverage, Emergency Turnaround & K3 Safety
Which provinces does Baskara Riau Teknik operate in?
Our physical engineering workshop is headquartered in Pekanbaru, Riau, strategically located to deploy engineers across 6 Indonesian provinces: Riau, West Sumatra (Sumatera Barat), Jambi, North Sumatra (Sumatera Utara), Bangka Belitung, and West Kalimantan (Kalimantan Barat). Our track record includes 8 completed projects for multinational agribusiness giant KLK Group across 5 different provinces.
Do you provide 24/7 emergency support during planned mill turnarounds or breakdowns?
Yes. We maintain an on-call emergency response engineering crew for industrial clients. During scheduled mill turnarounds or unexpected switchboard failures, our technicians can deploy rapidly with calibrated secondary injection test sets, Hipot testers, and certified cable termination kits to restore plant power safely.
What safety (K3) procedures are enforced during high-voltage works?
All site operations comply with strict occupational safety guidelines: certified 20 kV Arc Flash PPE, Lockout/Tagout (LOTO) protocols on incoming feeders, calibrated voltage detectors before earthing switch engagement, and certified crane rigging protocols. Lead engineers hold certified SKK Level 5 competencies recognized by the Ministry of Energy and Mineral Resources (ESDM).
5. Commercial Inquiries & Request for Quotation (RFQ)
What information is needed to receive a formal engineering quotation?
To provide an accurate, transparent proposal, please share: 1) Electrical Single Line Diagram (SLD) or load summary, 2) Preferred component brands (Schneider, ABB, etc.), 3) Substation site location/province, and 4) Target energization turnaround date. Inquiries can be submitted via our RFQ form or directly sent to our engineering WhatsApp.
Do you provide warranties on fabricated panels and installation work?
Yes. All switchgear cubicles and LVMDP panels fabricated by Baskara Riau Teknik include a comprehensive 12-month engineering workmanship warranty post-commissioning, alongside official manufacturer warranties on circuit breakers and distribution transformers.
