A flexible circuit is shown that limits current or removes power in response to a command from the user or other fault-indicating signal. It accommodates manual-reset (MR), over-temperature, and ...

This application note is intended to assist the user of Solid State Subscriber Line Interface Circuit (SLIC) and Line Card Access Switcht (LCAS) devices in meeting the stringent requirements of ...

Power protection is like insurance: You pay for it, yet hope you don’t need it. But it’s not a simple “purchase.” The first protection question is, “What am I seeking to protect and against what event ...

To be competitive, some electrical contractors often supply low-voltage (LV) service entrance switchboards and switchgear that meet the minimum safety requirements of the National Electrical Code (NEC ...

Most switching power-supply controllers provide non-latching fault protection. Satisfying a requirement for a latchoff response to a fault often requires the addition of excessive and redundant ...

Power™ Stage ICs deliver fast fault shutdown, 100% duty-cycle operation, and a single-input PWM option to simplify ...

How you should treat the neutral conductor depends on your system design. Neutral conductors must be grounded to prevent inadvertent potentials on conductive surfaces of equipment, enclosures and ...

For modern distribution protection, Negative Phase Sequence (NPS) Protection is often relegated in favor of common elements such as Overcurrent (OC) or Earth Fault (EF), but NPS is an incredibly ...

Power systems today operate in an environment where reliability and safety must be maintained despite rising loads, expanding interconnections, and increasing dependence on distributed energy ...

NOJA Power has released an upgrade to its OSM series reclosers with recloser control (RC), implementing fault location capability. Available as a free firmware upgrade on currently installed RC10 and ...
