A Relay Protection Tester is designed to simulate electrical quantities such as current, voltage, frequency, and phase, ...

Insulation resistance testers, often called megohmmeters, are fundamental tools for preventive maintenance, used to assess the integrity of insulation in motors, cables, transformers, and other ...

Power systems today operate in an environment where reliability and safety must be maintained despite rising loads, expanding ...

The small, lightweight PTE-50-CE is the ideal instrument to test overcurrent and over/undervoltage protective relays, among many other applications. The reversible 100-VA amplifier can inject up to ...

The objective of protective relays and protective schemes is to protect electrical equipment such as transformers, lines, cables, bus bars, etc. during abnormal system conditions. Hence, protective ...

Proper selection and effective testing can increase contact reliability in the end product while reducing the overall cost of using relays. Who said relays are pass�? While electromechanical relays ...

Relays are electromechanical devices that use a magnetic solenoid to actual a switch. When current is passed through the solenoid coil, it produces a magnetic field. The magnetic field is strengthened ...

Electronic relays have evolved a lot since their introduction in the early '30s, but their basic purpose hasn't changed. Transistors and integrated circuits have replaced vacuum tubes and the term ...
