SAMon from SCOPE is a powerful Online Leakage Current Monitoring system for continuous monitoring of metal oxide (Zno) Surge Arrester leakage current in live EHV / UHV substations.

It consists of portable Field Unit which is intalled near SA in IP enclosure, a PC at control room on which SAMon software is intalled and a Communication link between the two.

SAmon monitors Third Harmonic Resistive Leakage Current (THRC) which reflects the healthiness of SA, as per IEC 60099-5 B2.

Field Unit contuinously measures THRC at pre-set time interval and sends to central PC located in control room for monitoring all SAs in substation, multiple Field Units are used.

SA 30i and SA 10i the Leakage Current Analyser and Leakage Current Meter from SCOPE are two state of the art on-line test system for Residual Life Assessment of metal oxide (Zno) Surge Arresters. The instrument measures and directly displays the values of resistive and total leakage current. it is capable to work accurately and safely in swithchyard upto 765kV.

SA30i measures Third Harmonic Resistive leakage Current (THRC) with system harmonic compensation in accordance with IEC 60099-5 B2 (which is best recommended), whereas SA10i, a hand held Leakage Current Meter measures THRC without system harmonic compensation in accordance with IEC 60099-5 B1.

UVSee TD90 is an innovative Non Destructive Equipment, that detects, pinpoints and documents flash arc corona and arcing partial discharge camera. Being with high sensitivity UVSee TD90 is a power tool to detect UV emission in full daylight with high signal from faraway and nearby sources. UVSee TD90 is an ideal predictive maintenance device for Transmission Lines and High Voltage Substations.

ULIRvision Gas infrared camera TG series are patented product, enable to scan and diagnose SF6 leaks even in small amounts in the electrical substations and equipment’s. As the SF6 is perfect dielectric to quench the arcs so it is widely used in gas Insulated Substations, Circuit Breakers and other switchgears but it has significant impact on global climate change. ULRIvision SF6 leak detector spots and detects gas leakage accurately with vivid thermal video images from ground level whether leakage is at nearby or from meters away.

The Infrared signals can’t be seen by human eyes, however all objects with a temperature above absolute zero emits infrared thermal radiations for that only thermal imaging cameras can convert infrared radiations into electrical signals to make it visible.

TI160 & TI384 with high thermal sensitivity of 65mk can identify the smallest temperature variation from the object and display it by excellent thermal images. A potential fault always coming with the partial overheat / overcool, so the user can locate overheated / overcooled part with ULRIvision’s Thermal Imaging Camera instantaneously and more detail analysis about fault can be done in Thermal Imaging Analysis Software.

A Decade resistance box is a enclosure containing number of precision resistors connected to panel terminals or contacts so that a desired resistance value can be obtained by withdrawing plugs or by setting multi-contact switches.

SCOPE offers High Resistance, High Voltage Decade Resistance Box - DecR designed using the high quality specially selected resistors. These range of high ohm resistance decades are ideal for variety of applications, having a voltage rating up to 5kV. It covers the resistance range from 1 kilo ohm to 1 tera ohm.

The EM4058 earth tester is a digital, microprocessor controlled instrument that allows to measure the earth resistance and ground resistivity (using Wenner´s method), as well as to detect parasitic voltages present in the ground. This instrument is suitable to measure earth systems in power substations, industries, distribution networks, etc., according to IEC 61557-5.

It is also suitable for soil resistivity measurements, in order to optimize the earth systems project. It is a fully automatic and easy-to-operate equipment. Before starting each measurement, the equipment will check that conditions are within appropriate limits and will notify the operator in case any abnormality turns up (too high interference voltage, too much resistance in test spikes, very low test current, etc). Then, it will look for the most suitable range and show measurement results in an alphanumeric display.

The EM4058 has a Frequency Scan feature that performs an earth resistance measure with all vailable frequencies automatically and calculates, displays and prints the average result besides the individual result of each frequency. Those results are saved on the internal memory. 

The instrument has four ranges that are automatically selected, covering measurements from 0.01 Ω up to 20 kΩ, which allows to obtain very accurate measurements for any kind of soils. During ground resistivity measurement, the operator may indicate the distance between spikes in order for the equipment to apply Wenner's formula and to show the resistivity value directly. 

The transmission towers are electrically grounded by ground wires and due to the existence of this connection, any attempt to measure a tower ground resistance by any conventional earth tester leads to wrong results. To make this kind of test feasible, TM- 25R is the appropriate tool for a fast, safe and reliable grounding resistance measurement in each tower at charged transmission lines, without disconnecting the ground wire. The equipment only measures the ground resistance of the Surveyed Tower, including its base.

SCOPE introduces, for the first time in the country, the most powerful Real Time On-Line system for continuous monitoring of Circuit Breaker performance in HV / EHV substations.

RTMon consists of Field Unit which is inatalled near CB in IP enclosure, a PC in control room loaded with RTMon software and the communication link between the two.

No. of CBs in one subatation can be monitored by installing one field unit per CB, and they will communicate with central PC.

These new CT/PT testers are based on low frequency and variable frequency methods which lead to the great reduction in weight and high knee point test range. With one button click, all test items of the current transformer test set, such as excitation, winding resistance, polarity, phase error, ratio, etc, can be performed automatically.

PCT200Ai is the current transformer test set can finish various tests of different transformers. Compared with PCT200i,its accuracy is higher.This CT analyzer can test the 0.2s class CT.Only this CT analyzer - the high-accuracy current transformer test set has passed the tests held by Wuhan High Voltage Research Institute.The max permissible error of ratio measurement is ±0.05% and max phase measurement is ±2min.
