Omicron DIRANA

Advanced Diagnostic Capabilities:
The DIRANA analyzes the dielectric response of insulation over a very wide frequency range, enabling detailed moisture assessment, identification of ageing effects, and evaluation of insulation integrity. Its revolutionary FDS & PDC+ algorithm delivers fast measurement times—up to 20× faster than traditional methods—allowing full frequency sweeps from 10 µHz to 1 kHz in less than 2 hours. Results are automatically compared and evaluated against international standards or customised limit values for reliable condition assessment.

Intuitive Operation:
Operated through Primary Test Manager™ (PTM) software, DIRANA simplifies test setup, execution and data management. PTM automatically generates test plans based on nameplate information and guides users through workflows, while also offering smart features for result evaluation and reporting.

Portable and Field‑Ready:
The DIRANA comes as a compact and rugged all‑in‑one test set, designed for easy transport and reliable performance in field environments. Its simple wiring concept with integrated guard connections accelerates setup and ensures consistent measurements on site.

Comprehensive Support:
Renting the OMICRON DIRANA from us includes access to technical support for setup, software integration, and troubleshooting, ensuring efficient and dependable testing operations across projects.

Trusted by Industry Professionals:
Widely used by utilities, transformer manufacturers, and service providers globally, DIRANA is recognised for its precision, speed and ease of use in dielectric insulation diagnostics. Its capabilities make it an essential tool for condition‑based maintenance, commissioning checks, and predictive asset management.
