Analyze transformer & high voltage electrical equipment fluids

THE Chem Lab can advise the appropriate tests and test packages for your equipment and monitoring needs. We provide guidance on sampling techniques (see Seminars) as well as referrals for third party sampling service providers.

Why analyze transformer and high voltage electrical equipment fluids?

This is a powerful methodology to indicate the presence of incipient faults and determine the overall operating condition of a unit.

Baseline analyses are required upon commissioning of equipment or in the absence of recent data. Regular analyses provide trending characteristics that reveal additional information.

Scheduled sampling help make proactive decisions protecting your fleet and ensuring uninterrupted service delivery.

Tests

THE Chem Lab offers a routine testing package that has powerful diagnostic value. Our routine testing package includes:

• Dissolved Gas Analysis (IEC 60567 / ASTM D3612C modified)

• Moisture Content (ASTM D1533B)
