Condition monitoring can help you uncover the secrets your electrical network may be hiding - so you can plan ahead, avoid preventable failures and keep things running smoothly.
But how do you get started? Or how do you make your existing program a success?

Partial discharge (PD) detection in transformers, cable terminations, high-voltage (HV) substation and plant equipment

Partial discharge (PD) detection is a valuable technique which allows you to find early indications of deterioration giving you time to plan a course of actions. The PDS200 is a partial discharge surveyor tool with EMI capabilities. It identifies and analyzes radio frequency (RFI) and lower frequency electromagnetic (EMI) emissions. These are associated with faulty or degraded insulation and other system defects. The PDS200 uses EMI analysis to discriminate between different defects and discharge sources in transformers, cable terminations, high-voltage substation and plant equipment.


Power apparatus and insulation testing

The M4100 is the industry standard for power apparatus and insulation testing. It's unique combination of test capabilities and artificial intelligence analysis software makes it the power industry’s most trusted Power Factor/Tan-Delta instrument. The M4100 instruments are used around the globe thanks to their comprehensive testing options, safety features and measurement accuracy. Testing is simple and accurate with the M4100 and Doble Test Assistant (DTA) software. You can then analyze your test results with the help of FRANK™, the First Response Analytics Knowledgebase, which provides clear recommendations and explanations.

The Dranetz HDPQ-SP, an IP65 rated Portable Power Quality analyzer

The successful Dranetz HDPQ® Portables are now also available in a IP65 rated housing for outdoor and harsh environments, along with other applications where an LCD display is undesirable.
The HDPQ and HDPQ - SP are the exact same instrument, but are in different enclosures. The HDPQ is a true hand-held portable instrument with a built in 7″, tablet-like touch LCD display. The HDPQ -SP has the same measurement and communications capabilities, but is housed in an IP65 enclosure without an LCD display.

The Dranetz HDPQ family of power quality instruments offers you the best in class monitoring capabilities available. It measures to all current industry standards, including IEC 61000-4-30 Class A, IEC 61000-4-7, IEEE 1159, IEEE 519, IEEE 1459, and more.
