MEMS hydrogen gas sensor for in-situ monitoring of ... for the hydrogen gas is compared with the hydrocarbons because they are common in transformer insulation oil. The sensor demonstrated higher responses (ΔV = ∼0.67 mv at 200 ppm) toward hydrogen gas compared to that of the other gases which indicate good selectivity to H 2. The high selectivity of Pd-Ni (3%) resistor array towards ...Author: Vijay V. Kondalkar, Vijay V. Kondalkar, Jihoon Park, Keekeun Lee

FIST 3-30 TRANSFORMER MAINTENANCE· PDF fileCheck for discolored copper and discolored insulation. Check for corroded and loose connections. Check for carbon tracking on insulation and insulators. Check for cracked, chipped, and loose insulators. If windings are found dirty, add filter material to air intake ports. Check fan blades for cleanliness; remove dirt and dust.
High-Voltage Bushing Maintenance and Testing Explained· Gaskets with poor seals are probably also leaking water and air into the transformer, in which case DGA samples should be obtained to check for high water and oxygen content inside the main tank. If oil levels are low and there is no evidence of external leaks, an internal leak could be present around the lower seal leading into the transformer tank.

Dry Type Transformer: What is it? | Electrical4U· When transformer secondary voltage drops abruptly due to increase in load, this regulation is called poor regulation. Poor regulation is due to transformer higher internal leakage reactance. So, leakage reactance is kept within 2% during design. Life Expectancy Life of the transformer depends on the breakdown of winding insulation due to temperature rising effect in winding due to overloading.
