Our products consist of various models for comprehensive testing of all types of circuit breakers from 6.6 kV to 765 kV, both AIS & GIS. Our Various models can be selected based on their tests
Various models to suit to specific application
Testing Circuit Breaker & Isolator in highly inductive environment like 765 kV is difficult. Right equipment needs to be used for various parameters to prevent from failure. Our equipment has been designed to meet testing requirement of all parameters quickly. Our range of products varies from Hand Held unit to ultra-portable units for taking care of all needs.
Testing Power Transformer up to 500MVA, Generator Transformer in highly inductive environment is difficult. Key to any plant or substation, failure of GT / Power transformer is considered to be the biggest loss due to its cost & time of replacement. Testing with ‘Right’ equipment becomes paramount importance to check healthiness and do condition-based monitoring to prevent transformer from failure by rectifying in time.
This is the interface between protection system and various faults takes place in electrical power system. Various tests are conducted to check its healthiness.

Battery is the ‘Heart of Power system’. Reliability of power system protection greatly depends on healthy battery bank. Power plant & generator excitation system, unable to give desiered voltage/power to protection system is essential for continous opetation. This is necessary to monitor batteries regularly for a better life.
Capacity / Discharge Tester
High voltage cables are not only expensive, takes lots of time and care for installation and maintenance. Testing equipment of high quality and accuracy is required for debugging faults over a period of time. We offer high voltage cable testing equipment which are user friendly, compact inbuilt with latest technologies.
capacitors, insulators, switchgear, buss duct, hot-line tools, aerial lifts, bucket liners, transformers and other loads that draw more current
Other Tests
Tan Delta, Power Factor, Partial Discharge, dielectric testing of rubber gloves, aerial lift liners, hot sticks,
Insulators, irrespective of its position and type, plays significant role to give electrical clearance in any voltage level. In view of this Healthy insulator is minimum requirement in any power system. Unfortunately, there are very few a technology is available to check its healthiness while in service. We have privilege of supporting one of the most trusted & proved Insulator testers in the world
Why is insulator testing so important?
Critical failure of Insulators can cause long term damages as well as equipment and financial loses. Live-line work requires that the insulators be in good condition for lineman safeties Outages due to insulator failure are costly
Insulators can be tested & various problems can be detected without power outrage.
Insulator Tester is a revolutionary instrument capable of determining the condition of all types of insulator strings, including critical suspension insulators, and making a determination if it is safe for live-line transmission work on AC transmission power lines of 69 kV to 1,000 kV.
Earth tester offering selective earth, soil resistivity, earth coupling and continuity measurements
Ergonomic, comprehensive and accurate Earth Tester offers direct access to all the measurements, compact, rugged and leak proof.
