Dissovled Gas Analyzer
ZTOM-400
The key challenge for asset managers is finding power transformers faults in their infancy, allowing more time for decisions to be made resulting in less expensive maintenance. Manual sampling of dissolved gas analysis (DGA) can result in delayed discovery of faults and often faults have progress causing dissoved gas analysis changes in transformer oil
ZTOM-400 monitors all key area within the main tank of the power transformer and correlates data for asset managers for early fault diagnoses and detection.
Transformer Turns Ratio
VRT10-E
The transformer turns ratio Test helps to identify problems such as shorted-turns or open-turns, incorrect connections, tap changer and internal magnetic core problems.
The VRE10-E provides several test templates and functions for transformers turns ratio measurement in current transformers, voltage transformers and power transformers, with the required current and voltage injection and corresponding integrated measurement capability.
Resistance Testing Meter
RTM40-E
A DC winding resistance measurement is a common diagnostic test performed on distribution and power transformers. This test can used to detect internal issues such as shorted turns, burnt or open winding, broken strands, poor connection, and problems with On-Load Tap Changers (OLTC).
The RTM40-E is injecting a direct current (DC) through the winding to be tested, to then measure the corresponding voltage drop and thus determine the winding resistance.
Transformer Bushing Monitoring System
ZTOM-TEM
The ZTOM-TEM performs all the test method including partial discharge detection in parallel with the power factor calculation.
PD is caused by defective insulation in high-stress areas, movement of energized parts, or design error where low-level discharge occur. Some type of PD may not present a problem, but others can develop into surface tracking or insulation failure, which can lead to bushing or transformer failure. The ZTOM-TEM also has the unique capability of monitoring event and trends which potentially could damage the transformer with Easy-to-Use Multi-Tool software.
