Partial Discharge Testing Equipment
AR700
PD Defect Location in High-Voltage Equipment Insulation by Acoustic Sensors To act on deteriorating insulation the source of PD must be known.The insulation defects produce partial discharges, which emits electrical impulses, radiation of electromagnetic waves as well as acoustic signals.The AR700 measures acoustic signals with multiple sensors spread over the transformer. Then the software determines the failure location using the time difference of all incoming signals. Finally, these coordinates are shown in a 3D model of the transformer. AR700 device is used for measuring of acoustic signals on the external surfaces of gas-insulated breakers and substations, power transformers and other tank high-voltage equipment. The acoustic signals are caused by partial discharges in the insulation, which is the sigh of the defects.The advantage of “AR700” device is the quick installation of the acoustic PD sensors on the external surface of high-voltage equipment tank. The sensors have magnetic holder that is why there is no need to de-energize the equipment for the sensors installation. “AR700” device has 4 syn-chronic channels for acoustic signal measurement. This gives the possibility not only to find the defects in the insulation, but also to locate them. The location function of the “AR700”device is unique for acoustic devices.

Micro-Ohmmeters
RMO-G Series
The RMO-G is a portable micro-ohmmeter designed for contact resistance measurement of non-inductive test objects and applications with increased safety requirement. It tests medium and high-voltage circuit breakers, disconnecting switches, high-current bus bar joints, cable splices, and different high-current links. Due to its Both Sides Grounded and Remote Control functionalities, the instrument accurately measures even in the most demanding environments, providing additional safety to testing personnel.The RMO800G is the most powerful portable micro-ohmmeter on the market with 800 A output current. RMO200G is our best seller in the USA. A user can choose the appropriate model depending on the output current requirement, from 100 A (RMO100G) to 800 A (RMO800G).We use an unbreakable plastic case with IP67 protective rating (with closed lid) for instruments’ housing. Although very portable and lightweight, RMO-G micro-ohmmeters have very high output power capabilities. High output voltage enables a wider measurement range at higher test currents. Consequently, it enables the usage of thinner/longer test cables. RMO-G generates a true DC ripple-free (less than 1 % ripple) current with automatically regulated test ramps. During the testing, it increases current before measuring and decreases current after the measurement. This significantly decreases magnetic transients and ensures great accuracy.Special current clamps measure a current through groundings when the instrument tests in Both Sides Grounded conditions. The instrument itself powers these clamps. If even higher safety level is required, the Remote Control feature enables the operator to perform measurements from distant locations.RMO-G instruments can store up to 500 measurements in internal memory. Also, they have a built-in thermal printer and USB flash drive available as an option. An additional option is the built-in High Precision module suitable for measurement of very low resistance, in the range from 1 to 30 µΩ, with 0,01 µΩ resolution.Our free DV Win software communicates with the RMO-G micro-ohmmeters via USB or RS232 interface. It allows a user to run the test remotely from a PC. Also, a user can download test results, analyze and generate fully configurable test reports through the software.

Circuit breakers are being tested during manufacturing, commissioning or maintenance stages. The most basic test requires timing measurement using circuit breaker timer. Their primary role is timing and motion measurement of medium and high voltage circuit breakers. Devices from CAT Standard series have suitable application in:electric power generation,distribution system,part of the electric power transmission system,contractors testing,and industrial environments.CAT Standard series meets the requirements of an easy to use circuit breaker timer and analyzer with an attractive price. Furthermore, they are portable and lightweight (weighs only up to 7 kg). Finally, the plastic case is unbreakable and has IP67 protective rating when the lid is closed.CAT Standard series includes five models:Three circuit breaker timers – CAT03, CAT31, and CAT61Two circuit breaker analyzers – CAT34 and CAT64CAT03 is a basic model intended only for timing measurement of main contact operations on the circuit breaker with one break per phase. Unlike CAT03, CAT31 has the possibility of circuit breaker operation initiation, coil current measurement, and auxiliary contact timing measurement. CAT61 differs in comparison to CAT31 by its ability to measure up to two breaks per phase.CAT34 and CAT64 are more advanced compared to CAT31 and CAT61, respectively, since they have additional analog channels. Also, they have the possibility of a travel curve recording.A user can download the test results to a USB memory stick or save it to internal memory. The CAT Standard series internal memory can store up to 500 test results (numerical and graphical data). Optional thermal printer prints test results in tabular and graphical form on 80 mm (3.15 inch) paper rolls. CAT Standard series instruments are compatible with DV-Win software. It provides full control of all CAT functions from a PC, as well as acquisition and analysis of test results.

Auto Reclose and Sync Check
Operating records for overhead power lines reveal that most faults are of a transient nature (e.g. lightning induced) & that service interruptions may be minimized by use of automatic reclosing of circuit breakers. An automatic reclosure of the circuit breaker, after the fault clears, provides improved service continuity & system stability. The 1B230 Series Reclose Relay provides for single or double shot automatic reclosing of circuit breakers, following interruption of supply due to a fault in the system.
