Monitoring Relays
A Monitoring Relay is a protective control device. The basic functions are to receive input signals, monitor and determine them, and output an alarm signal if a set value (threshold) is reached. Monitoring Relays monitor power supplies (voltage, current, power, phase), temperatures, and other analog signals and detects abnormalities in machines and equipment by determining values against alarm thresholds.

Relay Test Set
Relay testing equipment is a portable apparatus designed for checking the operating characteristics of protective relays on site. Rr Relay Testing Equipments are designed to facilitate routine test or periodic maintenance test of relays by simulating (as early as possible) fault conditions under which the protective relays are required to function. There are several approaches to the method of testing relays on site. The Relay Testing Equipments are secondary injection type and are intended to be used to test the relays after isolating them from live systems, either physically or electrically.

Primary Current Injection Testers
Primary Current Injection Tester is designed for testing protective relay and circuit breakers and also testing the turns ratio of current transformers at high variable currents. A test current is injected into the primary side of a system to determine how the system behaves at particular levels of current. This test makes it possible to determine whether the relay will trip and how long the current needs to flow before the trip is initiated.

Three-Phase Transformer Demagnetizer
DEM60C
After a DC current test, such as winding resistance measurement, the magnetic core of a power or instrument transformer may be magnetized (remnant magnetism). It can cause various problems such as wrong diagnostics, inaccurate measurements on a transformer, inrush current at the start-up of a power transformer, or incorrect operation of protective relays due to magnetized CT cores. The best way to eliminate this source of potential problems is to use demagnetizer on the power or instrument transformer.The DEM60C is a fully automatic test instrument which performs three-phase transformer demagnetization. Transformer magnetic core demagnetization requires the application of AC current with magnitude decreasing to zero. DEM60C provides this AC current by internally changing the polarity of a controlled DC current. During the demagnetization process, the instrument supplies the current at decreasing magnitude for each step, following a proprietary algorithm. It can demagnetize single-phase and three-phase power transformers.The instrument can be connected to all three phases of a power transformer to be demagnetized, on either the primary or the secondary side. If a user selects specific vector diagrams for different types of transformers, DEM60C will run a specific demagnetization procedure for each transformer type (i.e., single phase, delta, wye/star, zig-zag.) without switching the test leads.DEM60C enables safe and efficient power transformer demagnetization. The instrument automatically regulates the injection of current and discharging energy from the inductance. During and after the operation, an intrinsically safe discharge circuit with an indicator rapidly dissipates the stored magnetic energy. The discharging circuit is independent of the power supply, which improves its reliability in case of loss of power.Test currents of up to 60 A DC enable efficient demagnetization of even the largest power transformers. Using a DV Win software, it is possible to control DEM60C externally.

Step Up Transformer
MagD
SCOPE proudly introduces Step-Up Transformer - MagD, specially designed to cater the needs of testing of instrument Transformers. Before new systems are put into service or after any occurrence of fault, the instrument transformers need to be tested for their outputs. It is to be ensured that these instrument transformers are giving proper outputs to the protective relays. MagD is used to plot excitation curves for instrument transformers. Inbuilt voltmeter and ammeter, eliminates the need of external meters for plotting of curves. It can also be used for de-magnetization of transformer cores and also turns-ratio tests can be conducted using MagD.

Sensing Resistors
Resistive Voltage Dividers
NGR Sensing Resistors are attached in parallel to the neutral grounding resistor. The sensing resistor allows a protective relay to detect a resistor failure in a continuous manner. Sensing Resistors are used in combination with neutral grounding resistor monitor relays. The relay measures neutral grounding resistance, neutral grounding resistor current and neutral to ground voltage. The relay continuously measures neutral grounding resistor ohmic value in an unfaulted system and it trips on if neutral grounding resistance varies from its calibrated value.
