Hilkar

Hilkar

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.

Circuit Breaker Analysis Systems

-

Megger Group Ltd.

Megger Group Ltd.

When a fault such as a short circuit or current overload is detected by a protective relay, a trip impulse is sent to the circuit breaker. The circuit breaker must function as specified and interrupt the current as soon as possible or severe damage may occur. The damage caused by a malfunctioning circuit breaker can often be catastrophic, resulting in significant damage to the electrical system.

Weshine Electric Manufacturing Co., Ltd

Weshine Electric Manufacturing Co., Ltd

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.

Arc-Flash Protection

Schweitzer Engineering Laboratories, Inc.

Schweitzer Engineering Laboratories, Inc.

Arc-flash detection technology significantly decreases the time it takes a relay to trip in response to an arc fault, thereby reducing hazardous incident energy. Combining light-sensing technology with fast overcurrent protection provides high-speed arc-flash detection and prevents overtripping for external faults. Arc-flash protection relays work with low- and medium-voltage apparatus and easily coordinate with other devices in utility-, industrial-, and commercial-scale power systems.

Hilkar

Resistive Voltage Dividers - Hilkar

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.
