Online Bushing Monitoring System

Online Bushing Monitoring System Bushing Monitoring Bushings have been identified as the cause of about 15{d985d444412a266f6028815d748e3bbbf46c6bab8291227b63da9f9cb54d1c3d} of all transformer failures. According to Doble, the leading cause of >100MVA transformer failure is bushing failure (35{d985d444412a266f6028815d748e3bbbf46c6bab8291227b63da9f9cb54d1c3d}). A Western Power survey of 2096 transformers in Australia and NZ found that bushing were only second to OLTC as the…

Online PD

Online PD Bushing Monitoring and Partial Discharge Detection for Transformers Bushings account for a large proportion of High Voltage (HV) substation failures often causing severe and costly damages. Preventive maintenance, early replacement and regular off-line testing have been employed to address this issue in the past. Now, technology exists that enables asset owners to detect…

Online DGA

Next generation On-Line Multi-Gas DGA Dissolved Gas Analysis (DGA) and moisture measurement of insulating fluids are recognized as the most important tests for condition assessment of transformers. In previous years, multi-gas DGA was traditionally confined to a laboratory environment, with infrequent off-line manual sampling forming part of time-based maintenance strategies. However, as the global average…

Portable DGA

Portable DGA Dissolved Gas Analysis (DGA) and moisture measurement of insulating fluids are recognized as the most important tests for condition assessment of fluid-insulated transformers. Every year asset owners deploy field crews to take thousands of fluid samples from transformers as part of periodic health checks and for immediate operational decisions. These samples are sent…

P – Micro DGA Analyzer

P – Micro DGA Analyzer This equipment can be used to detect the incipient fault in the transformer  and  arrest deterioration/damage to the transformer insulation by analyzing gases dissolved in the transformer oil and adopt preventive measures. The P Micro DGA/TOGA is capable to detect PPM & Sub PPM gases in transformer oil and can b configured for analysis as per IS10593 IEC…

Xenon – Krypton Determinator

Xenon – Krypton Determinator XENON-KRYPTON DETERMINATORS have been designed for normal sample size as well as for large diameter sample size of 20 mm (To be specified in advance). This Determinator is different than the Oxygen-Nitrogen and Hydrogen Determinators as here Xe and Kr are trapped at -60°C, and absorbed at 400°C, with temperature span…

Head Space TOGA Analyzer

Head Space TOGA Analyzer The Touch Screen GC System Model Dhruva  S2TS (NTPC & ERDA Approved) is configured for Dissolved Gas Analysis of transformer oil. It can be built to  meet the specification / Standards as per ASTM D 3612  Section A or C or IEC 60567, 2005 Section 7.3 or 7.5 as required by…
