Ugrarupa Energy Services Transformer & Electrical Equipment Testing

Service Overview

Ugrarupa Energy provides comprehensive testing and diagnostic services for transformers and electrical equipment used in renewable energy projects. Our specialized testing services include winding resistance, OLTC (On-Load Tap Changer), insulation testing, transformer ratio, dissolved gas analysis (DGA), and complete electrical safety assessments ensuring optimal performance and reliability.

Transformers are critical components in power generation and distribution systems. Regular testing and maintenance prevent catastrophic failures and costly downtime. Professional Testing & Diagnostics Services identify potential issues before they escalate. Our certified engineers utilize advanced testing equipment and follow ANSI/IEEE and IEC standards to conduct thorough assessments including oil analysis, bushing testing, protection relay verification, and complete electrical system diagnostics ensuring compliance, safety, and long-term reliability.

Comprehensive Testing Services

We deliver end-to-end transformer testing services from factory acceptance tests (FAT) to on-site commissioning and annual maintenance testing. Our services cover power transformers, distribution transformers, inverter transformers, step-up transformers, and complete electrical systems including switchgear, circuit breakers, protection relays, and auxiliary equipment for solar, wind, and hybrid renewable energy installations.

Winding Resistance Testing

Measurement of winding resistance to detect loose connections, damaged windings, and internal conductor defects.

OLTC Testing & Maintenance

On-Load Tap Changer inspection, contact resistance testing, oil analysis, and mechanical operation verification.

Insulation Testing

Insulation resistance, power factor, tan delta, and partial discharge testing to assess insulation health and integrity.

Oil Analysis & DGA

Frequently asked questions

Regular transformer testing prevents unexpected failures, extends equipment lifespan, ensures safety compliance, maintains warranty validity, and optimizes system performance. Our comprehensive testing services identify issues early, minimize downtime, and ensure reliable operation of electrical infrastructure throughout renewable energy installations.

We conduct winding resistance, transformer ratio, insulation resistance, power factor, tan delta, OLTC operation, oil analysis (DGA), dissolved moisture, dielectric strength, acidity, bushing testing, partial discharge detection, thermographic inspection, and complete electrical safety assessments following ANSI/IEEE and IEC standards.

We recommend annual transformer testing for critical equipment, biannual oil analysis, commissioning tests for new installations, pre-energization testing after long shutdowns, and immediate testing if abnormal operation is detected. Regular testing prevents failures, ensures safety, and extends transformer lifespan significantly.

DGA tests transformer oil to detect and measure dissolved gases produced by electrical or thermal faults. Gas ratios indicate specific problems like overheating, arcing, partial discharge, or cellulose degradation. Early detection through DGA prevents catastrophic failures, identifies maintenance needs, and extends transformer life.
