Pioneering the future of power testing and monitoring
CONFIGURABLE COMPLEX TRANSFORMER MONITORING SYSTEMS
Single gas DGA monitoring
Dissolved gas analysis in the transformer has been used for decades as a reliable tool for indication and prevention of faults. According to international standards for maintenance of transformers and in accordance with the rulebook for testing of HV equipment this analysis is mandatory. DGA is a powerful diagnostic technique for monitoring some of the possible faults in the transformer and trend the progress
The Immersed Tank Sensor is a DGA monitoring unit. It is capable of monitoring hydrogen, temperature , moisture and oil degradation directly from the transformer tank by permanently mounting on a flange. It has no moving parts (like pumps membranes gears etc. and uses solid state nickel palladium sensor for H2 measurement. No spare parts maintenance or recalibration are required in the min 15-year lifetime.

Fault gas Analyzer
The Transformer FGA is fault gas monitoring unit which is designed for smaller transformers to prevent serious faults in the earlier stage , plan outage and replacement and evaluate asset condition It is capable of monitoring hydrogen gas generation, methane generation, moisture and complete fault gas pressure.
PD monitoring
Partial discharge monitoring offers the fastest response to detect insulation imperfections or faults in windings insulation ,oil and bushings which result with free electrons movement inside the affected area. With this technology voids, insulation degradation and weak spots can be identified, trended and constantly monitored.
Bushing capacitance and tan delta monitoring
Bushing are relatively cheap (comparing to transformer value). Unfortunately, bushings breakdown failure often leads to catastrophic transformer failure like windings deformations. Due to materials imperfection weather conditions and stress bushings are prone to failure. Unfortunately, sometimes that failure escalates very quickly. Historically bushings were tested off-line to measure the capacitance and the dissipation / power factor.
The Bushing BMC Monitor is a permanently installed on-line bushing monitoring system. It continuously measures up to six leakage currents, tests the power factor and capacitance values and monitors the condition of bushings, CCVT`s 1) and free-standing CT`s.
The bushing monitoring system incorporates three measurement modes for standard and two for optional configurations.
Standard configuration with 6 current inputs:
- Sum of three current test
- Adjacent phase reference test
- Phase comparison
Optional configuration with 3 voltage and 3 current inputs:
- Reference test (3 bushings and 3 CCVT`s 1))
Optional configuration with 6 voltage inputs:
- CCVT 1) Reference test (6 CCVT`s 1))
The bushing sensors / adapters are connected to the capacitor taps designed for all types of bushings to allow measurement of the leakage current up to 140 mA AC.
Transformer leakage current monitoring
The POWER VIEW TLCM is permanently installed on the transformer grounding terminal. Monitors real time insulation leakage currents on the grounding terminal. This helps in early detection of all transformer’s insulation problems. Using smart algorithm and additional sensors integrated- the interferences and outdoor discrepancies are eliminated and the sensors measure true insulation leakage current.
The monitoring system is available is available in several configurations starting from 1 phase version, 3 phase version, 6 phase version . All versions are available in various IP protection classes starting from indoor to outdoor IP65 installation. The power supply is 5V DC and it can be either network, solar or battery supply unit. The power consumption is less than 1mA!
OLTC DGA monitoring
The DGA units incipient stage, before they develop into major faults and result in the outage of the transformer. The conventional BUCHHOLZ RELAY is universally used in transformers to protect against severe damages. However, its limitation is that enough gas must be generated first to saturate the oil fully and then to come out or there should be a gas surge to operate this relay. Moreover, Buchholz Relay is never meant to be a diagnostic device for preventive maintenance of transformers.

It is capable of monitoring hydrogen gas generation, methane generation, moisture and complete fault gas pressure.
