THE POWER BEHIND POWER
Assembly, installation, commissioning, and dismantling of transformers - Transformer and Tap changer maintenance (all types) - Oil leak repairs on transformers - Passivation and Inhibitor dosing of transformer oil - Main cover welding on transformers and on-site modifications - Re-spray of transformers - Spares sourcing - Oil sampling and interpretation of analysis - Corrosion treatment of electrical equipment
The purpose of a tap changer is to regulate the output voltage of a transformer. It does this by altering the number of turns in one winding and thereby changing the turns ratio of the transformer. There are two types of transformer tap changers: an on-load tap changer (OLTC) and a deenergised tap changer (DETC) and MND ELECTRICAL SOLUTIONS does the services maintenance and the sells of them.
Insulators can be divided into porcelain insulators, tempered glass insulators, compound insulators and semiconductor insulators, according to the different insulating materials. Composite insulators have an insulating part made up of a rod with a fiberglass resin core and a sheath of organic material..
