• Did you Know That...
  • 80% transient surge activity originates from within your facility (inductive & capacitive loads) while 20% transients originate from without (utility company) which include lightning strikes, grid disturbances, switching operations, defective transformers & faulty transmission lines etc?
  • IEEE C62.41 Electrical std recommends layered or cascading surge mitigation (class A, B & C)
  • That an AVR /AVS or UPS is not a SPD?
  • The power outage of August 14 2003 in the eastern part of North America left 50M people in the dark? 61,4800 MW of load was disrupted for up to 4 days. When power came back, people lost electronic equipment.
  • Sinetamer is a hybrid microprocessor based SPD with a product warranty of up to 25 years against failures?
