High Resistance Neutral Grounding Devices
-
HRG systems limit the fault current by placing high resistance between neutral point of transformer (or generator) and ground. As it is not possible to locate the fault point in delta connected systems, an artificial neutral point is created and delta connected system can be grounded. This allows a fault current of a few amperes thus locating the fault point gets easy. When the neutral point is grounded thru high resistance, both continuity of operation is provided during fault condition and sufficient current (typically between 2 A and 10 A) flow is provided for ease of locating the fault point.

LV Iron Core Harmonic Filters
-
Nonlinear loads such as power electronics based equipment and electric furnaces are sources of harmonic currents leading to harmonic distortion, which is one of the most important parameters for defining the power quality. Most of the commercial loads such as personal computers, photocopy machines, power supplies, and compact fluorescent lamps; and industrial loads such as AC and DC motor drives inject harmonic currents into the network that they are connected to.

High Current Transformers
-
High Current Transformer is designed to elevate and check the temperature of the conductors at high current levels, in order to simulate the current loading conditions found in electrical circuits. High Current Transformer is designed as an open type transformer that uses the test object as its secondary coil or has 1 or 2-turn self secondary winding. The conductors cores' temperature depends on the short-circuit high current caused by the test object. According to the current going through the test object, the test temperature of the conductor will change. The loop temperature is measured by a thermocouple probe which is directly connected to conductor.

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.
