B-1007 -
ROSS ENGINEERING CORPORATION
Extra high voltage, low corona, grounding relays of the air insulated type. Peak test ratings up to 300kV and 100 amps continuous. Units can be operated either by solenoid, motor, or air cylinder, with spring or gravity return. All models have spherical contacts. When voltage transient limiting is required, some models have an adjustable sphere gap. Also available are units with built-in high voltage discharge resistors with energy dissipation capabilities from 50 to 10,000 ohms. Some units can be reduced in height if full line to ground voltage is connected to the top high voltage contact only and the other high voltage terminal is operating at, or near, ground potential. Line to ground voltage can also be increased by adding insulation between lower high voltage contact and ground. Normally mounted base down. Base up mounting if specified.

TAURUS PRECIOHM ET -
Taurus Powertronics Systems
The TAURUS PRECIOHM ET is one of the specially designed products by TAURUS to measure earth resistivity and earth resistance in a power station. These tests are performed based on 4 point (Wenner) and 3 point (fall of potential) methods respectively. All electrical equipment in the substation and power stations are electrically connected to station earth mat with earth electrodes. The earth electrode ensures that in the event over voltage on the system due to system fault or lighting discharges etc., the parts of the equipment which are normally ”dead” as far as voltages are concerned; do not attain dangerously high potentials. An earth electrode will only be effective so long it has a low resistance to the earth and can carry large currents without deteriorating. Thus the resistance of earth electrode should be low to give good protection and it must be continuously measured and monitored in all the substations and power stations.

Neutronics Manufacturing Co.
Measure DC resistance of transformers windings etc. Introduction: The NMC ''TDR'' is a high precision, new generation, light weight large output current and micro-processor controlled tester. This replaces old DC wheat stone bridge and double arm bridge for measurement of DC resistance. ''TDR'' adopts new advanced test current power supply technology, four terminal measurement, digital display of resistance value and test current. ''TDR'' is powered by 220V AC mains single phase supply. The measurements are accurate as the test current is highly stable. High automation is achieved with automatic discharge warning.Principle: The constant current generated is fed to the resistance under test through the current terminals and the voltage drop across the resistance under test is measured and displayed in ohms. A true four terminal measurement is used to eliminate the need for lead resistance compensation.

Handheld Turns Ratio & Winding Resistance Tester TWR-H -
Amperis sl
TWR-H is a handheld, battery operated, fully automatic test set specially designed for turns ratio, phase shift, excitation current and winding resistance measurements of transformers. It can also perform demagnetization of these transformers. Transformer turns ratio is determined by applying AC voltage across high voltage winding, accurately measuring AC voltage across the corresponding unloaded transformer winding, and then displaying the ratio of these voltages. User can enter a transformer’s nameplate voltages, so that turns ratio deviation can be calculated. This feature eliminates any error otherwise caused by an operator’s manual calculation. TWR-H compares measured turns ratio with the nameplate ratio and prints out the % of error for each test. Transformer winding resistance is determined by injecting DC current through a winding, accurately measuring DC voltage across the winding, and then calculating resistance as the ratio of voltage and current. The device generates true DC ripple-free currents. Both the injection of the current and the discharge of energy from transformer magnetic circuit are automatically regulated.

Oersted Technology
The Model 300-series magnetizers are designed to handle a variety of magnetizing applications and materials, from small Alnico parts to large blocks of neodymium-iron. Each of these magnetizers feature patented ECS (Electronic Capacitance Switching) technology, which allows the user to change the capacitance of the unit through the front panel. By setting the charging voltage and capacitance of the magnetizer properly, the user can then scale the output energy of the unit to match the magnetizing fixture being used. The 300-series magnetizers also includes a peak current meter, which automatically captures the peak current of the magnetizing pulse once it occurs. A safety circuit internally discharges the capacitor banks if mains power is removed from the magnetizer or if the cabinet is opened during operation. When connected to a suitable magnetizing fixture, the magnetizer is able to disable its front panel controls if the fixture overheats. Other features include a lockout keyswitch and a current sense output jack (this connects to an oscilliscope for viewing of the magnetizing pulse). All 300-series magnetizers can be modified for computer control, photocell trigger, or autocharge operation.
