• The signal sources are the reference; no additional reference meters are required.
• 14 voltage / current generators in one device.
• Test Universe software with unrivaled manual and automatic testing functionality.
• OMICRON Protection Testing Library & test templates for the most important relays.
• Highest quality, safety, reliability and robustness.

5. Automatic Capacitance & Tan Delta Test Set

• Make – Eltel
• Model – ACTS-12K Plus
• Eltel Automatic Capacitance & Tan Delta test set is designed to conduct Power Factor tests on electrical insulation.
• The test set is capable of automatically measuring the insulation Power Factor of multi-terminal equipment at voltages ranging from less than 1 KV up to 12 KV.
• Being equipped with two measuring leads, the test sets can measure all the quantities associated with multi-terminal electrical power equipment.
• In addition to measuring the Capacitance and Power Factor of insulation, the test sets can measure the excitation current of transformers and other equipments.

Objectives of the Test:-
Tan Delta, also called Loss Angle or Dissipation Factor testing, is a diagnostic method of testing cables, bushings & windings of transformer, generators, and large motors to determine the quality of the insulation. This is done to try to predict the remaining life expectancy and in order to prioritize the corrective actions. It is also useful for determining what other tests may be worthwhile.

6. Thermal Imaging Camera 

• Make – FLIR
• Model – E30
• Thermal Imagers capture image of infrared energy or temperature.

Thermal Imaging, detects heat patterns or temperature changes in objects. These changes allow the user to discover problems prior to costly downtime.
